U2 Test Part 1: Cellular Respiration

Question 1

What is the most important part of cellular respiration

Answer 1

That it enables organisms to utilize stored energy in glucose

Question 2

What is the chemical difference between anaerobic and aerobic

Answer 2

Aerobic takes place in mitochondria and requires oxygen and glucose to produce carbon dioxide, water and energy.

Whereas anaerobic also uses energy and glucose but does not require oxygen

Question 3

Which is more efficient:

Aerobic

or

Anaerobic

Answer 3

Aerobic produces 38 ATP!

whereas anaerobic produces 2 ATP

Question 4

Energy consuming steps in glycolysis

Answer 4

In the first half of glycolysis, energy in the form of two ATP molecules is required to transform glucose into two three-carbon molecules.

Question 5

Lactic Acid Fermentation

Answer 5

is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution

Question 6

Acetyl- CoA (acetyl coenzyme A) function

Answer 6

main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.

Question 7

Cytochrome transport electron train

Answer 7

carry electrons from one complex of integral membrane proteins of the inner mitochondrial membrane to another

Question 8

Ph of the matrix and Intermembrane space

Answer 8

matrix has a pH of about 7.8

inter membrane space 7.0–7.4

Question 9

Enzyme that makes ATP

Answer 9

The ATP synthase- localized in the inner membrane

catalyzes the synthesis of ATP from ADP and phosphate

Question 10

Where is there an isomer in cellular respiration?

Answer 10

Glucose-6-phosphate is converted into its isomer, fructose-6-phosphate
