Light dependent reactions of phtosynthesis

Front

What is the thylakoid?

Back

The thylakoid is a membrane-bound structure within chloroplasts that contains chlorophyll and is the site of the light-dependent reactions of photosynthesis.

Front

How many membranes does a chloroplast have?

Back

A chloroplast has two membranes: an outer membrane and an inner membrane.

Front

What is the stroma in a chloroplast?

Back

The stroma is the fluid-filled space surrounding the thylakoids in a chloroplast, where the Calvin cycle occurs.

Front

What is the function of ATP synthase?

Back

ATP synthase is an enzyme that creates ATP from ADP and inorganic phosphate during the light-dependent reactions of photosynthesis.

Front

What are the two main products of the light-dependent reactions?

Back

The two main products of the light-dependent reactions are NADPH and ATP.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the light-dependent reactions.

Front

What is the significance of the light-dependent reactions?

Back

The light-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle.

Front

Where do the light-dependent reactions take place?

Back

The light-dependent reactions take place in the thylakoid membranes of the chloroplasts.

Front

What is photolysis in the context of photosynthesis?

Back

Photolysis is the process of splitting water molecules using light energy, producing oxygen, protons, and electrons.

Front

What is the role of water in the light-dependent reactions?

Back

Water provides electrons through photolysis, which are essential for the production of ATP and NADPH.
