| What happens during the light-dependent reactions of photosynthesis? |
|
Definition
-
light energy is absorbed by photosystem II, which breaks down water into O2, e-, and H+
-
H+ diffuse through the enzyme ATP synthase, which spins and energizes ATP
-
Photosystem I absorbs light energy, which energizes electrons, which are used to energize NADPH for the Calvin Cycle

Term
| What happens during the Calvin Cycle? |
|
Definition
| CO2 is turned into C6H12O6. ATP becomes ADP and NADPH turnes into NADP+ in the process. Both of these are returned to the light-dependent reactions to be re-energized. |

Term
|
Definition
| The process in respiration that breaks down glucose into pyruvic acid, which makes 2 ATP and 2 NADH. |
|
|
Term
|
Definition
| the process that follows glycolysis in the presence of oxygen; breaks down pyruvic acid and other carbon molecules to release CO2, NADH, FADH2, and 6 ATP. |

Definition
follows the Krebs cycle...
-
the electron carriers NADH and FADH2 interact with a protein channel in the lipid bylayer of a mitochondrion which realeases e-, H+, NAD+, and FAD
-
the H+ ions move into the intermembrane space, the electrons pass through the proteins, and the electron carriers go back to glycolosis
-
the high concentration of H+ ions in the intermembrane space make them go through the ATP synthase, which spins and energizes 24 ATP
-
energy from electrons is used to turn oxygen into water:
e- + H+ +O2 ---> H2O

Term
| What is the effect of oxygen on the ability of cells to make ATP? |
|
Definition
| Without oxygen, cells will be able to make 2 ATP with glycolysis, but otherwise can make none. |
