1. Enzymes from thermophilic organisms are useful in industrial processes that require high temperatures because they are thermostable and thermoactive, meaning they are robust and can perform optimally at high temperatures. 2. speeding up metabolism within the body including that involved in innate and adaptive immunity as well as tissue repair. 3. Higher temperatures increase kinetic energy, causing more denaturation. 4. optimize a high activity at low temperatures at the expense of substrate affinity, therefore reducing the free energy barrier of the transition state. 5.

* During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the grana stacks. Some of the light energy is converted to chemical energy. During this process, phosphate is added to a molecule to cause the formation of ATP. * Light-dependent reactions: Light energy is absorbed by chlorophyll in the thylakoid membranes, exciting electrons to produce ATP and NADPH while splitting water molecules to release oxygen. Calvin cycle (light-independent reactions): Using ATP and NADPH, carbon dioxide is fixed into organic molecules through a series of enzymatic reactions in the stroma, ultimately synthesizing glucose. * Leaves maximize light absorption by having a large, flat surface area, containing a high concentration of chloroplasts with chlorophyll pigment, which efficiently captures sunlight. * The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. * The Calvin cycle, also known as the light-independent reactions, contributes to the synthesis of glucose in plants by fixing carbon dioxide (CO2) into organic molecules and using the energy from the light-dependent reactions to produce glucose. * Light intensity, carbon dioxide concentration, and temperature are the three main limiting factors affecting photosynthesis.

* Environmental factors such as light, temperature, and humidity affect gaseous exchange in plants by influencing the rate of transpiration and the density of stomata on leaves. * The presence of numerous stomata, tiny pores on the leaf's surface, enables the rapid exchange of carbon dioxide and oxygen. * Aquatic plants have their roots submerged in water. To facilitate gaseous exchange in such plants, roots grow erect above the ground. * A plant's cuticle controls the rate of gaseous exchange when stomata close, and limits the amount of gas exchange that can occur. * Gases in the intercellular spaces between spongy mesophyll cells are free to move out of the stomata into the atmosphere, and atmospheric gasses are free to move in.

* The net photosynthetic rates under red light and blue light were significantly greater than under the other light wavelengths. The net photosynthetic rates under green light and yellow light were significantly lower than under white light. * the rate of photosynthesis is proportional to the chlorophyll content when the latter is varied by varying the iron supply. * Rate of photosynthesis increases as the temperature rises, but only up to a certain level. * it indicates when a plant is performing as much photosynthesis as possible and when high light intensity could start to damage the plant. * A higher number of stomata and a longer period of their opening promotes absorption of C O 2 and hence the rate of photosynthesis increases.

1. The waxy cuticle on date palm leaflets helps the plant survive in arid environments by reducing water loss through the leaves. 2. Most stomata are located on the bottom of leaves, or the ventral portion. The main reason for this is to control water loss from evaporation, as water can be lost when the stomata open to allow gas exchange. The more sunlight hits an area, the more water it will lose. 3. The fibrous structure of date palm leaves provides flexibility and strength, allowing them to bend without breaking and reducing water loss, which helps the plant withstand dry and windy conditions. 4. If date palm leaves were broad and thin instead of narrow and leathery, they would lose more water through transpiration and be more prone to damage from strong winds, reducing their ability to survive in harsh desert climates. 5. Date Palm Leaves (Desert Environment): * Narrow and leathery structure: Minimizes water loss by reducing surface area and preventing excessive transpiration. * Fibrous and flexible: Allows them to withstand strong winds without breaking. * Thick cuticle: Reduces water evaporation and offers protection from intense sunlight. Rainforest Plant Leaves: * Broad and thin structure: Maximizes surface area for efficient photosynthesis in a low-light, dense canopy environment. * Drip tips: Facilitate the shedding of excess water from frequent rain, preventing fungal growth. * Soft, pliable texture: Adapted for quick growth and easy light capture without needing resistance to harsh climates.

* Guard cells regulate the opening and closing of stomatal pores by increasing or decreasing the amount of water in them. * Veins are very important for transporting water and nutrients throughout the leaf. * Dicot leaves are not as linear in shape as monocot leaves, and their vascular structures form net-like veins, instead of parallel ones. * Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield. * Spines or hairs shade plants and break up drying winds across the leaf/stem surface.

1. Impurities can decrease the percentage yield by interfering with the reaction process or by contaminating the final product. 2. Control reaction conditions: Carefully monitor the reaction and maintain the correct temperature and stirring.  Add reagents slowly: Add reagents dropwise to ensure they react fully.  Use clean glassware: Avoid contamination by using clean glassware and pure reagents.  Optimize isolation and purification: Use separation techniques like distillation, crystallization, or filtering to extract and purify the product.  Remove impurities: Remove impurities from the reactants.  3. evaluates the efficiency of a process by comparing the yield of product actually obtained to the maximum yield predicted by stoichiometry. 4. Percentage yield The ratio of the actual yield to the theoretical yield of a chemical reaction.

It's calculated by dividing the mass of the pure substance by the total mass of the sample and multiplying by 100.  5. by comparing the amount of product actually obtained to the maximum amount that could have been produced. 6. Pharmaceutical production: High percent yields in drug synthesis can reduce costs and waste.  Environmental considerations: Higher yields usually mean fewer byproducts and less waste.  Manufacturing: In the production of complex chemicals, even one step with a low percent yield can lead to a large waste of reactants and unnecessary expense. 7. decrease the percentage yield of a chemical reaction.

1. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. 2. The products of photosynthesis are glucose and oxygen. 3. Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis. 4. The Calvin cycle uses the chemical energy of ATP and the reducing power of NADPH from the light-dependent reactions to produce sugars for the plant to use.

* Impact of Cloud Cover: Prolonged cloud cover reduces solar energy reaching the surface, slowing evaporation and precipitation. This can lower water availability in ecosystems reliant on regular rainfall, such as tropical forests. * Ozone Layer's Role: The ozone layer absorbs most harmful UV radiation. Depletion increases UV exposure, raising risks of skin cancer, cataracts, and damage to ecosystems. * Wind Patterns: Differential heating creates pressure gradients that drive winds. Example: Offshore wind farms use sea breezes caused by land heating faster than water during the day. * Solar Energy Adoption: Benefits include reduced greenhouse gas emissions and decreased reliance on fossil fuels. Limitations involve high initial costs, energy storage challenges, and dependency on sunlight. As for the 5th question... I haven't even talked about calculating potential energy yield anywhere in this post. I have not mentioned the formula or anything, and i have no idea what is solar irradiance.
