Photosynthesis Biology

Photosystems are made of

• chloroplasts

• chromosomes

• chlorophyll

• cytoplasm

ATP is made during the light reaction using all of the following EXCEPT

• proton pump

• hydrogen ion gradient

• electron energy from photosystem II

• NADPH donating electrons

What is FALSE about the calvin cycle

• uses the light reactions products

• produces a three carbon sugar (G3P)

• produces carbon dioxide

• produces NADP+

What begins the process of photosynthesis?

• carbon dioxide is diffused into the stroma to, in a series of reactions, create sugar

• Water is split apart to release electrons and create a hydrogen concentration gradient

• ATP and NADPH energize reactants to produce oxygen and glucose

• Light energy is absorbed by pigments to energize the electron transport chain
