Define cellular respiration, and state where it takes place. Identify the three stages of cellular respiration. How many molecules of ATP are produced in each stage?
Explain how cellular respiration and photosynthesis are related.
Compare and contrast aerobic and anaerobic respiration.

Cellular respiration is the oxidation of food substances coupled with the release of energy (ATP). It occurs in the mitochondria of living cells.

b. 38 ATP in animals. In plants 2 ATP.

Anaerobic respiration is one that that takes place in the absence of oxygen while aerobic respiration is one that requires oxygen to take place.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
