The main difference between anaerobic and aerobic refers to the presence or absence of oxygen during the processes:

1. Aerobic: This requires oxygen. In aerobic processes, such as aerobic respiration, organisms (like humans) use oxygen to convert glucose into energy (ATP).This happens in the mitochondria of cells and produces a lot of energy, along with carbon dioxide and water as byproduct.

• Aerobic respiration is the process of producing energy using oxygen.

• It happens inside the mitochondria of cells.

• Glucose (from food) is broken down with oxygen to make ATP (energy).

• The byproducts are carbon dioxide and water.

• This process produces a lot of energy and is efficient.

• It’s used by most organisms, including humans, for daily activities like breathing, moving, and growing.

2. Anaerobic: This occurs without oxygen. Anaerobic processes, like anaerobic respiration or fermentation, also produce energy but in a much less efficient manner than aerobic respiration. For example, in muscle cells during intense exercise, anaerobic respiration can lead to the production of lactic acid (in animals) or ethanol and carbon dioxide (in yeast).

•It breaks down glucose (sugar) to release energy.

•Less energy is produced compared to aerobic respiration.

•The byproducts can be lactic acid (in animals) or ethanol and carbon dioxide (in yeast).

•It happens in situations where oxygen is limited or absent, like in muscles during intense exercise or in some microorganisms.

•It is less efficient but helps organisms survive temporarily when oxygen is unavailable.

WHAT IS RESPIRATION 

Respiration is the process that produces energy in cells.

• It involves breaking down food (usually glucose) to release energy.

• Oxygen is used in aerobic respiration, but some organisms can do it without oxygen (anaerobic respiration).

• The main energy produced is called ATP.

• Carbon dioxide and water are the byproducts of respiration.

• Respiration happens in all living organisms for survival.

Are fishes Aerobic or Anaerobic.

The truth is fish’s they are both anaerobic and aerobic.

• Fish rely on aerobic respiration (with oxygen) to produce energy.

• They get oxygen from the water through their gills.

• Oxygen is absorbed into the blood, then transported to cells.

• In cells, aerobic respiration occurs, producing energy (ATP) for activities like swimming and eating.

• Low oxygen environments (like stagnant water or high heat):

• Some fish can switch to anaerobic respiration (without oxygen) temporarily.

• Anaerobic respiration is less efficient, producing less energy and sometimes harmful byproducts like lactic acid.

• Adaptations to low oxygen:

• Fish like carp can survive in low-oxygen water for short periods using anaerobic respiration.

• Mudskippers and other species can breathe air or get oxygen from the surface to survive in oxygen-poor environments.

• Overall, most fish are aerobic but have adaptations to survive in low-oxygen conditions when needed.
