Anaerobic start of respiration in all organisms
Oxidized in the Krebs cycle to carry electrons to
oxidative phosphorylation
Occurs when excited electrons from chlorophyll
have no place to go but back to ground state
Long term storage molecule in plants
What two ATP molecules are used for inithily in
glycolysis
Molecules created by chemiosmosis and a proton
gradient
Reactant and product of the Krebs cycle
Organelle for aerobic cellular respiration
Addition of a phosphate group to a molecule
Colour of light, around 500 mu, used most
efficiently for photosynthesis
Excess ATP can inhibit the action of this enzyme
(recall feedback inhibition!)
Organelle for photosynthesis
Can limit the rate of photosynthesis
This can be measured in batches of plants as an
indicator of rate of photosynthesis
Product of glycolysis that can enter a number of
different pathways
Addition of carbon dioxide in a reaction
Reaction that involves the loss of electrons
Oxaloacetate binds to an acetyl group to form this
compound
Accessory pigment absorbing in the yellow orange
range
Electron carrier produced by reduction reactions in
respiration
I
42. Projections of the mitochondrial inner membrane
to increase surface area
46. Plant parts that allow diffusion of carbon dioxide
in and oxygen out
47. Non-excited state for an electron
49. One of the products of photosynthesis
50. Fixation of this requires hydrogen from photolysis
and energy from ATP
52. Reaction that converts pyruvate into acetyl CoA
53. Reactant and product of the Calvin cycle
54. Fluid inside the chloroplast containing enzymes
for the Calvin cycle
55. General term for thep of molecules
1.
These stacks increase the surface area available for
photosynthesis
2. Explains how electron flow, proton gradients and
ATP synthase produce ATP
-3. Removal f carbon dioxide in a reaction
4. Gradient created by proton pumps
5. Light colour at wavelengths around 680-700 urn;
used efficiently for photosynthesis
6. Photosystem using P700
7. Products are alcohol and carbon dioxide
8. Photosynthetic rate can be measured using the
volume of these gas bubbles produced by aquatic
plants
8. Final electron acceptor in aerobic cellular
respiration
11. Photosystern using P680
12. Product of fermentation in yeast
13. Total ATP generated by oxidation Of tine glucose
molecule in glycolysis
15. Main pigment used to absorb light
19. Another name for the cycle involving
light-independent reactions
20. Groups of hundreds of chlorophyll molecules and
accessory pigments
23. Spectrum graph that shows the percentage of the
wavelengths of visible light absorbed
25. Light dependent breakdown of water to form
protons, electrons and oxygen
26. Light that is reflected by chlorophyll
28. Membrane where light dependent reactions occur
31. Reaction that involves the gaining of electrons
36. Ribulose bisphosphate carboxylase-oxygenase
38. State of electrons when light is absorbed by
chlorophyll
39. Photophosphorylation. involving only
Photosystem I
41. Spectrum graph that shows the percentage use of
the wavelengths of light in photosynthesis
43. Fluid inside the mitochondrion containing
enzymes for the Krebs cycle
44. As the intensity of this increases, photosynthetic
rate will eventually plateau
45. Product of anaerobic respiration that accumulates
in muscle tissue
48. Created in non-cyclic photophosphorylation; used
in the light independent reactions
51. Another name for the citric acid cycle
