Cell Metabolism

Question 0

What are metabolic patterns?

Answer 0

The processes of the metabolism that degrade food molecules and synthesize macromolecules needed by the cell.

Question 1

What is the metabolism?

Answer 1

Is the summary of all the biochemical reactions in the cells in order to maintain life.

Question 2

Glucose oxidation in order to obtain ATP

Answer 2

Glycolysis

Question 3

Acetyl-coa oxidation in order to obtain GTP

Answer 3

Krebs’ cycle

Question 4

Disposal of the electrons released by glycolysis and Krebs’ cycle and stored as ATP.

Answer 4

Oxidative Phosphorylation

Question 5

Synthesis of pentoses and release of the reducing power needed for anabolic reactions.

Answer 5

Pentose Phosphate Pathway

Question 6

Disposal of NH4+ in less toxic forms

Answer 6

Urea Cycle

Question 7

Fatty acids breakdown into Acetyl-coa, to be used by the Krebs’ cycle.

Answer 7

Fatty acid b-oxidation

Question 8

Glucose synthesis from smaller precursors, to be used by the brain.

Answer 8

Gluconeogenesis

Question 9

Two categories of the metabolism

Answer 9

Catabolism and anabolism

Question 10

What is catabolism?

Answer 10

Comes from the world cata that means destruction, involves oxidation and the release of energy

Question 11

What is anabolism?

Answer 11

The synthesis of complex molecules, usually involves reduction and requires the cell to expend ATP.

Question 12

What are the reactions that yield energy?

Answer 12

Exergonic reactions, partner of catabolic reactions

Question 13

Reactions that require an input of energy are?…

Answer 13

Endergonic reaction, partner of the anabolic reactions.

Question 14

What are the four classes of macromolecules?

Answer 14

1-Polysaccharides
2-Lipids
3-Nucleic acids
4-Proteins
They are synthesized by anabolic reactions.

Question 15

Type of catabolic reaction

Answer 15

Hydrolysis

Question 16

What are enzymes?

Answer 16

They are protein catalysts that speed biochemical reactions.
