Cellular Respiration

Question 1

When delta G is positive, energy is…

Answer 1

Absorbed (endergonic)

Question 2

Phosphorylation

Answer 2

The process of adding energy and an inorganic compound to ADP to make ATP

Question 3

Substrate level phosphorylation

Answer 3

when a phosphate group and its associated energy are transferred to ADP to form ATP (the substrate donates he ugh energy phosphate group). Example: glycolysis

Question 4

Oxidative phosphorylation

Answer 4

When a phosphate group is added but the energy comes from electrons

Question 5

Three steps of aerobic respiration

Answer 5

Glycolysis, Krebs Cycle, electron transport chain

Question 6

Glycolysis

Answer 6

The decomposition of glucose to pyruvate. Steps: 2 ATP added. 2 NADH produced. 4ATP produced. 2 Pyruvate formed.

Question 7

Krebs cycle

Answer 7

Steps: Puruvate to acetyl CoA. For each pyruvate:

Creates 3 NADH, 1 FADH(2), 1ATP and 2 co(2).

Question 8

Four areas of the mitochondria

Answer 8

Outer membrane
Inter membrane space
Inner membrane. Convulsions are cristae. ETC happens here.
Matrix. Inner fluid. Krebs cycle happens here

Question 9

How does chemiosmosis work?

Answer 9

Energy is stored in the form of a proton gradient between the inner membrane and the inter membrane space. Think energy produced when turbines forced to spin

Question 10

Two kinds of anaerobic respiration

Answer 10

Alcohol fermentation: takes place in the cytoplasm, frees up NAD+ by using NADH to make acetaldehyde, then ethanol. Does this so that glycolysis
Lactic acid fermentation: same idea, just converts a pyruvate to lactate

Question 11

When delta G is negative, energy is…

Answer 11

Released (exergonic)
