Question 7

a process where living plant cells combine carbon dioxide & water, in the presence of chlorophyll & light energy, to form carbohydrates and release oxygen as the waste product

Answer 7

photosynthesis

Question 8

two stage of photosynthesis

Answer 8

light reaction - photolysis
dark reaction - carbon-fixation

Question 9

Answer 9

1st stage - light reaction - photolysis

Question 10

where does photolysis occur

Answer 10

thylakoids

Question 11

Answer 11

2nd stage- dark reaction - carbon-fixation

Question 12

where does dark reaction occur

Answer 12

stroma

Question 13

Answer 16

aerobic

Question 17

2 cell respiration

Answer 17

glycolysis
fermentation

Question 18

the enzymatic breakdown of a carbohydrate to produce pyruvic acid and energy stored ATP

Answer 18

glycolysis

Question 19

the breakdown of pyruvic acid w/out the use of oxygen

Answer 19

fermentation

Question 20

3 major stages of aerobic

Answer 20

glycolysis
krebs cycle
electron transport

Question 21

stage of aerobic where breaking down of glucose molecules occur from carbohydrates into pyruvate
2 ATP, 2H2O, 2 NADH

Answer 21

glycolysis

Question 22

stage of aerobic called citric acid cycle; pyruvate processed to release ATP

Answer 22

krebs cycle

Question 23

where does glycolysis takes place

Answer 23

cytosol of the cell

Question 24

stage of aerobic where remaining energy from glucose will be released by electron transport chain.

electron & protons are added to oxygen = H20 is produced

Answer 24

electron transport

process where RNA is made from DNA

Answer 28

transcription
