Multiple Choice
Which of the following is a similarity between photosynthesis and cellular respiration?
A
Both processes occur in the mitochondria.
B
Both processes require sunlight to occur.

D
Both processes produce oxygen as a byproduct.
Verified step by step guidance

Begin by understanding the basic purpose of photosynthesis and cellular respiration. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose. Cellular respiration is the process by which cells convert glucose into usable energy in the form of ATP.
Identify the main components involved in each process. Photosynthesis primarily occurs in the chloroplasts of plant cells and involves the conversion of carbon dioxide and water into glucose and oxygen using sunlight. Cellular respiration occurs in the mitochondria of both plant and animal cells and involves the conversion of glucose and oxygen into carbon dioxide, water, and ATP.
Recognize the role of energy conversion in both processes. Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration converts chemical energy from glucose into ATP, which is used by cells for various functions.
Consider the byproducts of each process. Photosynthesis produces oxygen as a byproduct, while cellular respiration produces carbon dioxide and water as byproducts.
Conclude that the similarity between photosynthesis and cellular respiration is that both processes involve the conversion of energy, albeit in different forms and directions. Photosynthesis converts light energy into chemical energy, while cellular respiration converts chemical energy into usable energy (ATP).
