chapter 9 - photosynthesis

Question 1

ATP

Answer 1

adenosine triphosphate; compound used by cells to store and release energy

Question 2

photosynthesis

Answer 2

process which plants use sunlight to create energy; converts CO2 to oxygen and energy

Question 3

photosynthesis equation

Answer 3

6CO2 + 6H2O → C6H12O6 + 6O2

carbon dioxide + water –> glucose + oxygen

Question 4

pigment

Answer 4

light absorbing molecules used by plants to gather the sun’s energy (e.g. cholorphyll A)

Question 5

chlorophyll

Answer 5

principal pigment of plants and photosynthesizers

Question 6

light

Answer 6

photon particle traveling on a wave

Question 7

granum

Answer 7

stack of thylakoids (looks like pancake stack)

Question 8

thylakoid

Answer 8

one of the “pancakes” in the chloroplast

Question 9

light-dependant reactions

Answer 9

reactions that use light to create ATP and NADPH; exists in granum stacks

Question 10

light-independant reactions (calvin cycle)

Answer 10

uses ATP and NADPH from light-dep. reactions to create glucose

Question 11

photosystem

Answer 11

cluster of chlorophyll and proteins found in thylakoids

Question 12

electron transport chain

Answer 12

the path of an electron across carrier proteins on a thylakoid

Question 13

ATP synthase

Answer 13

“peanut” shape spinning protein on thylakoid membrane that creates ATP and NADPH

Question 14

NADPH

Answer 14

nicotinamide adenine dinucleotide phosphate (modified nucleotide); accepts and holds two high-energy electrons on an H+ ion, carries them to calvin cycle
