Metabolism

Question 1

Metabolism

Answer 1

How cells use energy to build, break apart, store and release substances in a controlled manner

Question 2

What r the 2 types of reactions in metabolism

Answer 2

Catabolism & Anabolism

Question 3

Catabolism

Answer 3

Breakdown of complex molecules into simpler ones; releasing energy in the process

Question 4

Anabolism

Answer 4

Consume energy to build complicated molecules from simpler ones

Question 5

Thermodynamics

Answer 5

Balancing energy that is transferred between molecules (input, output)

Question 6

1st law

Answer 6

Energy in the universe is constant; cannot be made or destroyed

Question 7

2nd law

Answer 7

Energy transformations are inefficient; they increase the entropy of universe (changes quality not quantity)

Question 8

Energy

Answer 8

Capacity to do work

Question 9

What type of energy do your cells need to do work ?

Answer 9

ATP- glucose/food

Question 10

What does ATP consist of

Answer 10

Sugar, base, 3 phosphate groups

Question 11

Phosphorylation

Answer 11

The chemical attachment of phosphorus to another molecule

Question 12

Substrate level phosphorylation

Answer 12

Transfer of a phosphate group to ADP, forming ATP

Question 13

Oxidative phosphorylation

Answer 13

ATP production from the transfer of electrons in electron transport chain

Question 14

3 classes of work that need ATP

Answer 14

-mechanical energy
-transport work
-chemical work

Question 15

Mechanical work

Answer 15

Contraction of muscle cell, beating of flagellum

Question 16

Transport work

Answer 16

Transporting substances in and out the cell, against con. gradient

Question 17

Chemical work

Answer 17

Making polymers from monomers

Question 18

Co factor

Answer 18

Helps enzymes transferring electrons, ions or functional groups from one site to another

Question 19

Cellular respiration

Answer 19

Process by which cells break down glucose to produce energy in from of ATP

Question 20

Fermentation

Answer 20

generating chemical energy in the absence of oxygen
-Limits CR to Glycolysis
-partial oxidation

Question 21

redox reactions

Answer 21

reactions where electrons get transferred from one atom to another

Question 22

ATP can also be produced by…

Answer 22

Fermentation

Question 23

what can fermentation produce

Answer 23

-ethyl alcohol or lactic acids
(both anaerobic)

Question 24

anaerobic

Answer 24

no oxygen needed to produce energy

Question 25

aerobic

Answer 25

oxygen needed to produce energy
