Metabolic Processes

Question 1

Glycolysis

Answer 1

10 step energy-yielding pathway where glucose molecules are first broken down, makes pyruvate

Question 2

Glycolysis requires

Answer 2

first 4 steps 2 ATP, later steps 4 ATP, therefore a net gain of 2 ATP

Question 3

Where does glycolysis occur

Answer 3

in the cytoplasm

Question 4

Krebs cycle

Answer 4

occurs in the mitochondrial matrix, and consists of a series of oxidation reactions to further break down glucose into CO2

Question 5

C4 plants

Answer 5

minimize photorespiration by continually pumping CO2 from mesophyll cells into bundle sheath cells in the vein of a monocot leaf

Question 6

CAM plants

Answer 6

open stomas at night, close during the day

Question 7

Pyruvate Oxidation

Answer 7

when oxygen is present pyruvate is oxidized and converted into acetyl Co A

Question 8

Photosynthesis 3 steps

Answer 8

1. capture light energy
2. use captured energy to reduce NADP+ to NADPH and synthesize ATP
3. Use free energy of ATP to synthesize organic compound of CxH2xOx from Co2 and H+ ions

Question 9

Calvin Cycle

Answer 9

Occurs in the stroma, as long as there is NADPH and ATP, the cycle will run

Question 10

Calvin Cycle limiting factor

Answer 10

Water and sunlight

Question 11

C3 plants

Answer 11

close their stomas on hot dry days so they do not lose water, can loose up to 25% of its mass before wilting and dying
