Energy

Question 1

How is ATP produced?

Answer 1

Substrate level phosphorylation and Phosphorylation

Question 2

Substrate level phosphorylation

Answer 2

phosphate group removed from intermediate reactant.

Free energy of reaction used to add phosphate to ADP.

Question 3

Oxidative phosphorylation

Answer 3

uses chemiosmosis and oxygen to produce ATP.

Question 4

Glycolysis

Answer 4

Occurs in cytoplasm; No requirement for oxygen; 1 glucose à 2 pyruvate; needs input of 2 ATP; total ATP 4 net 2 and 2 NADH

Question 5

Oxidation of pyruvate

Answer 5

Occurs in mitochondria; requires oxygen; 2 pyruvate à2 acetyl CoA; Produces 2NADH per molecule of glucose

Question 6

Citric Acid Cycl

Answer 6

Occurs in matrix of mitochondria; requires oxygen; Know total production of ATP, NADH, FADH2 per molecule of glucose

Question 7

Electron Transport Chain

Answer 7

Proteins located on inner mitochondrial membrane; Electrons from NADH and FADH2 donated to electron transport chain proteins- Energy used to pump H+ from matrix to intermembrane space; Finale electron acceptor is oxygen; ATP synthase- Allows H+ to diffuse from intermembrane space to matrix,Uses energy to make ATP; chemiosmosis

Question 8

Anaerobic Respiration

Answer 8

Occurs if oxygen is absent; Converts pyruvate to something that can be eliminated and converts NADH to NAD+;In muscle pyruvate is converted to lactic acid; In yeast pyruvate is converted to ethanol; No energy (ATP) produced
