2
What molecule is oxidized to donate electrons for photosynthesis?
3
H 2 0 is oxidized and donates it ’ s electrons to the reaction centre of photosystem II
4
What are the products of the light reaction in photosynthesis?
5
ATP and NADPH
6
1 turn of the Clavin Cycle generates this 3 carbon molecule:
7
PGAL (Phosphoglyceraldehyde) which when combined with another PGAL forms Glucose
8
Which molecule gets reduced in the light dependent reactions of photosynthesis?
9
NADP is reduced as it gains electrons and hydrogen to form NADPH
10
In photosynthesis, a chemiosmotic gradient of this molecule allows ATP synthase to produce ATP.
11
A hydrogen gradient is created across the thylakoid membrane a this differential gives ATP synthase enough energy to produce an ATP.
12
This phase of cellular respiration does not require oxygen
13
Glycolysis does not require O 2 and initiates aerobic as well as anaerobic respiration.
14
What is the net production of ATP from Glycolysis?
15
2 ATP are produced in glycolysis.
16
Name the two coenzymes that transport hydrogen in mitochondria.
17
NAD and FAD are the coenzymes that transport hydrogen.
18
What is the net production of ATP from lactic acid fermentation?
19
The only 2 ATP are from glycolysis
20
How many NADH molecules are produced in ethanol fermentation?
21
None – the two that are produced in glycolysis are used when converting pyruvate to ethanol
22
How many ATP (net) are produced in aerobic cellular respiration
23
36 Total ATP
24
Each NADH contains enough energy to produce _____ ATP ’ s
25
3 ATP ’ s per NADH 2 ATP ’ s per FADH
26
The Kreb ’ s cycle produces CO 2. Where else in cellular respiration is CO 2 emitted?
27
2 CO2 molecules are lost in between Glycolysis and the Kreb ’ s cycle (in the production of Acetyl-CoA)
28
What is the net production of ATP from ethanol fermentation?
29
2 ATP molecules are produced in the Glycolysis phase of anaerobic respiration
30
Which NADP generate more energy for the cell, those produced in the cytoplasm or those produced in the mitochondria?
31
Those produced in the mitochondria generate more energy as they don’t need to be transported into the mitochondria
32
What do enzymes do?
33
Catalyze / speed up reactions
34
Co-enzymes are similar to enzymes. Name one that is important for photosynthesis.
35
NADP is a coenzyme used in photosynthesis
36
What is the name of the enzyme that breaks eliminates H 2 O 2 from our tissues?
37
Catalase
38
Name 3 conditions that affect the speed of a reaction
39
Temperature, pH, Surface Area, Amount of enzyme, Amount of substrate / product
40
The name of the enzme responsible for fixing CO 2 from the atmosphere in the Calvin Cycle.
41
Rubisco
42
What is the first law of thermodynamics?
44
What is the second law of thermodynamics?
46
What does it mean to be “ oxidized ” ?
48
What is the name for the reaction when light energy splits a water molecule?
50
How many fish are there in the MCHS fishtank?
