The products produced in the light independent reaction are used to drive the light dependent reaction.
a. true
b. false

False

Explanation:

Light independent reactions of photosynthesis produce glucose from carbon dioxide. Glucose is the ultimate product of photosynthesis which is used by plants as a source of energy.

The light-dependent reactions of photosynthesis include photolysis of water molecule and release of electrons to drive the synthesis of ATP and NADPH. The electrons are transferred from water molecule to the PSII, carrier, PSI and finally to the NADP+ to reduce it into NADPH.

During the electron transfer, the generated proton gradient drives the ATP synthesis. ATP and NADPH formed during light reactions are used in light-independent reactions of photosynthesis.

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
