Cell Metabolism

Question 1

What are the 3 types of Cellular Respiration

Answer 1

External:outside to alveoli and lungs
Internal: gas exchange between blood to tissue
Cellular: oxygen and nutrient to break down ATP to create energy by product.

Question 2

Oxidation

Answer 2

Loss of electrons where you lose hydrogen and replace with oxygen

Question 3

What is the most oxidized form of Oxygen

Answer 3

CO2

Question 4

Cellular respiration chemical reaction

Answer 4

C6H1206+6O2—-> 6CO2+6H2O+ATP

Glucose is oxidize by adding in O2, oxygen is then inhale to give CO2 during this cells make ATP

Question 5

ATP

Answer 5

Adenine Triphosphate is reactive, and reusable

ADP CAN MAKE ATP again

Question 6

Glucose to ATP occurs in 4 steps

Answer 6

Glycolysis
Pyruvate Decarboxylation
TCA (Kerbs Cycle )
ETC ( Electon transport chain

Question 7

Glycolysis is

Answer 7

The breakdown of glucose
It occurs in the cytosol of cells
Is anaerobic( doesn’t require oxygen)

Question 8

How many Pyruvate molecules form from 1 glucose molecule

Answer 8

2

Question 9

Hexoinase is an Enzyme

Answer 9

Is the first step in glycolysis
It adds a phosphate group to glucose
Its irreversible
Stops glucose from leaving

Question 10

Phosphofructokinase (PFK)

Answer 10

Is the 2nd limiting step, produce Fructose-1,6 bisphosphate

When you see this know that pfk has done it’s job

Question 11

At end glucose gives

Answer 11

2NADH, 2ATP, 2 Pyruvate molecules

Question 12

Where does Pyruvate decorboxylation, kerbs cycle, ETC occur

Answer 12

In the mitochondria matrix

Question 13

Where does ATP production takes place?

Answer 13

in the mitochondria

Question 14

Pyruvate decarboxylation

Answer 14

Occurs in the mitochondria matrix

by secondary CoA ( coenzyme A)

Question 15

Is Pyruvate Decarboxylation reversible or irreversible

Answer 15

Irreversible

Question 16

How many Pyruvate molecules are give by glucose in glycolysis

Answer 16

2 Pyruvate molecules

Question 17

Kerbs Cycle is

Answer 17

Aerobic requires 02
Takes place in mitochondria
Requires energy

Question 18

In the Kerbs cycle

Answer 18

Acetyl CoA is made by Pyruvate Decarboxylation connects with oxoloacetate to form CITRATE

Question 19

In 1 Kerbs cycle

Answer 19

3 NADH, 1 FADH, 1 GTP, and 2xCO2 are produced

Question 20

What are the products going to be if glycolysis under goes 1 cycle in Kerbs

Answer 20

6 NADH, 2FADH2, 2GTP, 4CO2

Question 21

ETC

Answer 21

Electron transport chain where most ATP Is produced

Occurs in inner membrane of mitochondrial
