Frequently Asked Questions
What is the main purpose of photosynthesis in cells?
The main purpose of photosynthesis is to convert light energy into chemical energy stored in glucose molecules, which can be used by the cell for energy and growth.
Where in the cell does photosynthesis occur?
Photosynthesis occurs in the chloroplasts, primarily within the thylakoid membranes of plant cells.
What are the reactants and products of photosynthesis?
Reactants: carbon dioxide and water; Products: glucose and oxygen.
How does cellular respiration relate to photosynthesis?
Cellular respiration breaks down glucose produced during photosynthesis to release energy in the form of ATP, completing the energy cycle in living organisms.
What are the three main stages of cellular respiration?
Glycolysis, the Krebs cycle (citric acid cycle), and the electron transport chain.
Where does cellular respiration take place in the cell?
Cellular respiration occurs in the mitochondria of the cell.
What are the main inputs and outputs of cellular respiration?
Inputs: glucose and oxygen; Outputs: carbon dioxide, water, and ATP.
Why are photosynthesis and cellular respiration considered complementary processes?
Because the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, and vice versa, creating a cycle of energy transfer in ecosystems.
