General Photosynthesis

1

In which organelle does photosynthesis take place?

Chloroplast

1

The gel-like liquid that acts as filler space inside the chloroplast

Stroma

1

What is the ultimate source of energy for the light-dependent reactions?

The sun/sunlight

1

Write the general reaction for photosynthesis

6 CO₂ + 6 H₂O = 6 O₂ + C₆H₁₂O₆

1

Which pigment is primarily responsible for capturing light energy?

Chlorophyll

The Light Dependent 1

1

What is the name of the process when water is split?

Photolysis

1

What gas is released as a by product of the light dependent reactions?

oxygen gas

1

During the first electron transport chain, protons (H+) are pumped in the _____________

Thylakoid space

1

During photolysis, water is split into what three products?

Oxygen gas, H+ (protons) and electrons

1

What are the 2 main products of the light dependent reactions?

ATP and NADPH

The Light Dependent 2

1

NADP+ is _______________ to NADPH by gaining electrons and protons.

reduced

1

Protons flow through ATP synthase. This step is called:

chemiosmosis

1

The thylakoid membrane consists of membrane bound proteins and a _________________ by layer. 

Phospholipid

1

Which molecule acts as the final electron acceptor in the light-dependent reactions?

NADP+

1

What is the point of photolysis?

To produce electrons to replace those used in the ETC

What is the main purpose of the light-independent reactions?

To produce glucose

1

What five-carbon sugar is involved in the Calvin cycle?

Ribulose bisphosphate (RuBP)

1

What is the primary product of the Calvin cycle?
