Photosynthesis Process: Stages and Key Components Explained

Question 1

Which organelle is the primary site of photosynthesis in plant cells?

Accepted Answer

c4

Answer

Nucleus

Answer

Mitochondrion

Answer

Golgi apparatus

Answer

Chloroplast

Question 2

Which pair of products is produced by the light-dependent reactions?

Accepted Answer

c1

Answer

$ATP$ and $NADPH$

Answer

Rubisco and $ATP$

Answer

Glucose and oxygen

Answer

Carbon dioxide and water

Question 3

Describe the role of chlorophyll in photosynthesis.

Accepted Answer

Chlorophyll absorbs light energy and transfers it to the photosynthetic electron transport chain, initiating the light-dependent reactions that produce $ATP$ and $NADPH$.

Question 4

Explain the main purpose of the Calvin cycle and where it occurs.

Accepted Answer

The Calvin cycle fixes atmospheric $CO_2$ into carbohydrate by using $ATP$ and $NADPH$ to produce triose phosphates that are assembled into glucose; it occurs in the chloroplast stroma.

Question 6

The light-dependent reactions occur in the {{b1}} and produce {{b2}} and {{b3}}.

Accepted Answer

b1: thylakoid membranes; b2: $ATP$; b3: $NADPH$

Answer

thylakoid membranes

Answer

$ATP$

Answer

$NADPH$
