Chapter 5

Question 1

The term for the sum of all chemical reactions within a living organism?

Answer 1

metabolism

Question 2

What is the main end product of Glycolyssis?

Answer 2

Pyruvic Acid

Question 3

Define Cellular Respiration or simply respiration.

Answer 3

is metabolism in the body that makes energy. Oxidation of molecules that gives electrons to help the electron transport chain. ATP generated by oxidative phsophorlyation.

Question 4

List the 4 factors that can influence enzymatic activity

Answer 4

Temperature
pH
Substrate concentration
Inhibitors

Question 5

Competative

Answer 5

Fill active site on enzyme and competes with substrate

Question 6

Non Competative

Answer 6

INteract with different part of enzyme called allosteric site which indirectly changes shape of active site making enzyme not functional.
Turn enzyme ON/OFF

Question 7

In aerobic respiration what is the final electron accepetor?

Answer 7

Oxygen

Question 8

in anaerobic respiration what is the final electron acceptor?

Answer 8

Inorganic molecules

Question 9

List at least 2 general end-products of Fermentation

Answer 9

Alcohol
CO2 Gas

Question 10

Briefly explain the difference between photoautotrophs and photoheterotrophs in their energy source and carbon source

Answer 10

Phototroph energy sources from light and paired with carbon
Photoheterotrophs are made from organic compounds and need to be ingested were photoautotrophs are made with CO2 and H2O can reduce making cyanobacteria and if not makes an oxygenic photosynthetic bacteria

Question 11

Briefly explain the difference between chemoautotrophs and chemoheterotrophs in their energy source and carbon source

Answer 11

Chemotrophs are an energy source coming from chemicals that piar with a carbon source. If the chemotrophs are carbon source pair with organic compounds this is called chemoheterotrophs and if they are paired with CO2 they are called chemotrophs.

Question 12

Catabolic

Answer 12

breakdown complex molecules providing energy and building blocks for anabolism exergonic

Question 13

anabolic

Answer 13

build up using energy building blocks to build complex molecules
Energonic

Question 14

collision theory

Answer 14

chemical reactions occur when atoms, ions and molecules collide

Question 15

What is the total of Catabolism and Anabolism in a coupling reactions

Answer 15

Total of both is metabolism

Question 16

Activation energy is

Answer 16

the collision energy required for a chemical reaction to occur

Question 17

Reaction rate is

Answer 17

frequency of collisions containing enough energy to bring about a reaction
How fast we can go

Question 18

Catalysts

Answer 18

speed up chemical reactions without being altered

Question 19

Enzyemes

Answer 19

are biological catalysts
act on specific substrate and lower activation energy
substrate = raw material

Question 20

Names of enzymes usually end in ase

Question 20

Substrate + enzyme active site =

Answer 20

Enzyme substrate complex

Question 21

Turnover number

Answer 21

number of substrate molecules an enzyme converts to a product per second
FAST
