How does cellular respiration depend on photosynthesis?

Answer 1

Aerobic respiration requires oxygen to produce energy and expels carbon dioxide. This ultimately depends on photosynthesis, because plants take the carbon dioxide out of the air and use it for photosynthesis, which expels oxygen into the air as waste.

Answer 2

Well, this is the equation of photosynthesis:

carbon dioxide + water + light energy (with chlorophyll) = glucose + oxygen

And this is the equation of respiration:

glucose + oxygen (with enzymes) = carbon dioxide + water + energy or ATP

Notice that the raw materials of respiration are the end products of photosynthesis and vice versa. So, cell respiration needs the end products of photosynthesis in order to function.

Answer 3

Cellular respiration relies on photosynthesis for the production of glucose, which serves as the primary energy source. Through photosynthesis, plants convert sunlight, CO2, and water into glucose and oxygen. During cellular respiration, glucose is broken down to release energy in the form of ATP, which is necessary for cellular functions.

Answer 4

Well one of the products of photosynthesis is oxygen, which is what we need to breathe.

Answer 5

Photosynthesis creates the glucose molecules required for glycolosis, the first step in cellular respiration.
