Unit 4: Cells And Energy - Photosynthesis

Question 1

ATP

Answer 1

adenosine triphosphate: an ester of adenosine and triphosphoric acid, (C 10 H 12 N 5 O 4 H 4 P 3 O 9 ), formed especially aerobically by the reaction of ADP and an orthophosphate during oxidation, or by the interaction of ADP and phosphocreatine or certain other substrates, and serving as a source of energy for physiological reactions, especially muscle contraction.

Question 2

CAM

Answer 2

Leaving the leaf stomata closed during the warm day

Question 3

C3

Answer 3

Photosynthesis is harmed if it is too hot out. It slows down.

Question 3

Chlorophyll

Answer 3

the green coloring matter of leaves and plants, essential to the production of carbohydrates by photosynthesis, and occurring in a bluish-black form, C 55 H 72 MgN 4 O 5 (chlorophyll a) and a dark-green form, C 55 H 70 MgN 4 O 6 (chlorophyll b)

Question 4

Question 8

NADPH

Answer 8

Reduced form of NADP+, with the addition of hydrogen

Question 8

Pigment

Answer 8

any substance whose presence in the tissues or cells of animals or plants colors them.

Question 9

Stroma

Answer 9

the supporting framework or matrix of a cell.

Question 10

Thylakoid

Answer 10

a flattened sac or vesicle lined with a pigmented membrane that is the site of photosynthesis, in plants and algae occurring in interconnected stacks constituting a granum of the chloroplast, and in other photosynthesizing organisms occurring either singly or as part of the cell membrane or other structure.
