Q

PHOTOSYSTEMS

A

CLUSTERS OF PROTEIN AND CHLOROPHYLL; THEY ABSORB SUNLIGHT AND GENERATE HIGH-ENERGY ELECTRONS

17
Q

ELECTRON TRANSPORT CHAIN

A

WHERE HIGH-ENERGY ELECTRONS ARE PASSED TO; PUMPS H+ INTO THYLAKOID

18
Q

ATP SYNTHASE

A

THE ENZYME THAT USES THE CONCENTRATION GRADIENT OF H+ IONS TO MAKE ATP

19
Q

ENERGY

A

THE ABILITY TO DO WORK

20
Q

ATP

A

A COMPOUND THAT CELLS USE TO STORE AND RELEASE ENERGY; ENERGY IN ATP IS RELEASED BY BREAKING THE 3RD PHOSPHATE; MOST USEFUL ENERGY TO POWER CELL ACTIVITY

21
Q
