PHOTOSYNTHESIS AND RESPIRATION QUIZ

Assume the combined processes of photosynthesis and cellular respiration, the electrons that start as part of H2O at the beginning of the light reactions end up attaching to

pyruvate to make ethanol

NADPH to make new glucose

O2 to make new H2O

electron transport carriers to make O2

TRUE ANSWER : ?
YOUR ANSWER : ?

The followings are the products of the light reactions of photosynthesis except

NADPH

glucose

ATP

oxygen

TRUE ANSWER : ?
YOUR ANSWER : ?

The manufacture of ATP in both photosynthesis and respiration is made possible by
