Question

Spaced Practice o 17) Photosynthesis and cellular respiration are found throughout the eukaryotic world. They are complementary to each other because they each use products of the other process. What do the two pathways share? What do the two pathways share? Now choose from one of the following options Why? chloroplasts and mitochondria Photosystems I and II the cytochrome complex thylakoids

Answer 1

Process of photosynthesis takes place in thylakoid of chloroplast in plant cell where it uses sunlight to produce food -

Sonlight + CO2 + Water $\rightarrow$ Glucose + O2

This glucose is stored in cells and is used when needed in the process of cellular respiration where glucose is used to produce energy for metabolic processes. The process of cellular respiration takes place in mitochondria.

Glucose + O2 $\rightarrow$ CO2 + Water + ATP (energy)

So the option a is correct only as the photosystem l and ll , cytochrome complex and thylakoid all have their role in process of photosynthesis and not in cellular respiration which takes place in mitochondria.

Answer 2

Thylakoids
