What happens in light-dependent reactions?

The light-dependent reactions produce oxygen gas and convert ADP and NADP⁺ into the energy carriers ATP and NADPH.

What is

the Calvin cycle?

The Calvin cycle uses ATP ad NADPH from the light-dependent reactions to produce high-energy sugars.

Thylakoid

A saclike body in chloroplasts made of photosynthetic membranes that contain photosystems (p. 208)

Stroma

A region outside the thylakoid membranes in chloroplasts (p. 209)

NADP⁺

nicotinamide adenine dinucleotide phosphate

One of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules (p. 209) 

light-dependent

reactions

Reactions of photosynthesis that use energy from light to produce ATP and NADPH (p. 210)

ATP synthase

Large protein that uses energy from H⁺ ions to bind ADP and a phosphate group together to produce ATP (p. 210)

Calvin Cycle

Reactions of photosynthesis in which energy from ATP and NADPH is used ot build high-energy from ATP and NADPH is used to build high-energy compounds such as sugars (p. 212)

Summarize

the light-dependent

reactions.

Give the definition of a light-dependent reaction:

The light dependent reactions produce oxygen gas and convert ADP and NADP⁺ into the energy carriers ATP and NADPH. 

What is

the function of NADPH?

It is one way in which some of the energy of sunlight can be trapped in chemical form.

How is light energy

converted into chemical energy

during photosynthesis?

Light energy is converted into chemical energy by the pigments of the chloroplast.
