AP biology: metabolism, cellular respiration, photosynthesis

Question 1

Catabolic reaction

Answer 1

Breakdown pathways of complex molecules

Question 2

Anabolic respiration

Answer 2

Consumes energy to build complicated molecules from simpler ones 
Bio synthetic
Uses energy
Endergonic
Non spontaneous
Positive delta G
Photosynthesis

Question 3

1st law of thermodynamics

Answer 3

Energy can not be created, nor destroyed.

Question 4

2nd law of thermodynamics

Answer 4

Energy transormation increases the entropy of the universe

For a spontaneous process to occur, it must increase the entropy of the universe.

Question 5

NAD+…

Answer 5

Is an electron acceptor

Question 6

Cellular respiration reactions

Answer 6

Glycolysis:
Glucose
Cytosol
Anaerobic
2 ATP
Forms NADH
2 pyruvic molecules

Converstion step:
Pyruvic acid
Mitochondrial matrix
Anaerobic
Forms NADH, CO2 (waste product)
Acetyl CoA

Question 7

Etc vs. Chemiosmosis

Answer 7

Etc:
no ATP
Result of ATP powers Chemiosmosis

Chemiosmosis:
Control release of energy into smaller steps
ATP synthase

Question 8

Fermentation

Answer 8

Anaerobic

Produces more NAD+ through the step of glycolysis

Question 9

Feedback mechanism

Answer 9

Low ATP: respiration speeds up

High ATP: respiration slows down

Question 10

Stomata

Answer 10

Co2 enters the leaf

o2 leaves

Question 11

Cellular respiration

Answer 11

If anaerobic, glycolysis is followed by alcoholic fermentation and lactic acid fermentation
If anaerobic, glycolysis is followed by the Krebs cycle, etc, and oxidative phosphorylation
