Q

What are metabolic patterns?

A

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

1
Q

What is the metabolism?

A

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

2
Q

Glucose oxidation in order to obtain ATP

A

Glycolysis

3
Q

Acetyl-coa oxidation in order to obtain GTP

A

Krebs’ cycle

4
Q

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

A

Oxidative Phosphorylation

5
Q

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

A

Pentose Phosphate Pathway

6
Q

Disposal of NH4+ in less toxic forms

A

Urea Cycle

7
Q

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

A

Fatty acid b-oxidation

8
Q

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

A

Gluconeogenesis

9
Q

Two categories of the metabolism

A

Catabolism and anabolism

10
Q

What is catabolism?

A

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

11
Q

What is anabolism?

A

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

12
Q

What are the reactions that yield energy?

A

Exergonic reactions, partner of catabolic reactions

13
Q

Reactions that require an input of energy are?…

A

Endergonic reaction, partner of the anabolic reactions.

14
Q

What are the four classes of macromolecules?

A
1-Polysaccharides
2-Lipids
3-Nucleic acids
4-Proteins
They are synthesized by anabolic reactions.
15
Q

Type of catabolic reaction

A

Hydrolysis

16
Q

What are enzymes?

A

They are protein catalysts that speed biochemical reactions.
