Ch 06 Cell Respiration

Question 0

Occurring without the use of molecular oxygen;

Answer 0

Anaerobic

Question 1

The presence of oxygen; requiring oxygen

Answer 1

Aerobic

Question 2

Catabolic pathways by which electrons are removed from various molecules and passed through intermediate electron carriers to Oxygen, generating water and releasing energy

Answer 2

Cellular Respiration

Question 3

Formation of ATP in mitochondria and chloroplasts, resulting from the pumping of protons across a membrane (against a gradient of electrical charge and of pH), followed by the return of the protons through a protein channel with ATP synthase activity.

Answer 3

Chemiosmosis

Question 4

In cellular respiration, a set of chemical reactions whereby acetyl CoA is oxidized to carbon dioxide and hydrogen atoms are stored as NADH and FADH2. Also called the Krebs Cycle

Answer 4

Citric acid cycle

Question 5

The passage of electrons through a series of proteins with a release of energy which may be captured in a concentration gradient or in Chemical form such as NADH or ATP

Answer 5

Electron transport

Question 6

The anaerobic degradation of a substance such as glucose to smaller molecules such as lactic acid or alcohol with the extraction of energy

Answer 6

Fermentation

Question 7

The enzymatic breakdown of glucose to pyruvic acid (pyruvate)

Answer 7

Glycolysis

Question 8

Relative loss of electrons in a chemical reaction

Answer 8

Oxidation

Question 9

ATP formation in the mitochondria associated with flow of electrons through the respiratory chain

Answer 9

Oxidative phosphorylation

Question 10

Conversion of pyruvate to acetyl CoA and CO2 that occurs in the mitochondrial matrix in the presence of O2

Answer 10

Pyruvate oxidation

Question 11

A chemical reaction in which one reactant becomes oxidized and the other becomes reduced

Answer 11

Redox reaction

Question 12

Gain of electrons by a chemical reactant

Answer 12

Reduction

Question 13

How many net ATP are produced in Glycolysis?

Answer 13

2

Question 14

What is the carbon compound that is a product of Glycolysis?

Answer 14

3C compound Pyruvate

and there’s 2 of them

Question 15

What carbon compounds result from the oxidation of pyruvate?

Answer 15

Acetyl CoA and Carbon Dioxide

2C + 1C

Question 16

Which pathway completely oxidizes the 2-carbon acetyl CoA to 2 molecules of carbon dioxide?

Answer 16

Krebs Cycle

citric acid cycle
