Energy and processes

Question 1

What is energy

Answer 1

The capacity to do work

Question 2

Energy can be neither

Answer 2

Created or destroyed

Only converter from one to another

Question 3

Metabolism

Answer 3

The sun of all chemical reactions in a cell

Question 4

Two types of reactions

Answer 4

Anabolic reactions

Catabolic reactions

Question 5

Anabolic reactions

Answer 5

Join atoms or molecules together using bonds to make bigger molecules

Question 6

Catabolic reactions

Answer 6

Break bonds of bigger molecules

Question 7

Hydrolysis is which kind of reaction

Answer 7

Catabolic reaction

Question 8

Polymerizing is what kind of reaction

Answer 8

Anabolic

Question 9

Examples of catabolic reactions

Answer 9

Breaking down protein to yeild amino acids

Breaking down a starch to yield glucose molecules

Question 10

Example of anabolic reactions

Answer 10

Building a protein using amino acids

Question 11

Enzyme:

Answer 11

A protein that speeds up a reaction without being changed by the reaction

Question 12

Catalysts

Answer 12

Reactants that are not used up in the course of a reaction, and can therefore be re-used

Question 13

Substrate

Answer 13

The molecule that an enzyme changes

Question 14

active site

Answer 14

Location where binding occurs

Question 15

Cofactors

Answer 15

Helpers for enzymes- they help the enzyme by helping them to bind their substrate or changing their shape to fit better

Question 16

Two ways to control an enzyme

Answer 16

Competitively

No competitively

Question 17

Competitive inhibition

Answer 17

They fit onto the substrate and don’t let go, so the competitive inhibitor competes for the active site with the original

Question 18

Non competitive inhibition

Answer 18

Reaction is blocked because binding of a regulatory molecule in regulatory site changes the confirmation of active site so that substrate cannot enter

Question 19

What happens when temp is too hot for enzyme

Answer 19

Enzymes denature and cannot be fixed

Question 20

What happens at slightly warm for enzyme

Answer 20

Enzymes encounter reactants more often, but may be sustaining damage usually do not work as efficiently

Question 21

Temp too cold for enzyme consequence/

Answer 21

Molecular movements slow down, enzymes are not efficient

Question 22

Perfect temp for enzymes consequences

Answer 22

Enzymes work at peak efficiency

Question 23

When energy is released, where does it go

Answer 23

We want to capture and use as much possible

Temporary energy storage molecule: ATP

Question 24

What is ATP

Answer 24

Sort of like money, using ATP to carry out energy reactions

Question 25

Celia load respiration’s

Answer 25

Taking the energy in for example glucose and breaking it down, removing that energy from glucose and making it into ATP.

Question 26

NAD
FADH
ADP

are what

Answer 26

Molecules needed to carry out glucose breakdown

Question 27

ATP molecule has three phosphates which makes it unstable so what happens

Answer 27

The third triphosphate breaks off and produces energy

Question 28

Aerobic respiration

Answer 28

Using oxygen in the respiratory process

Question 29

Anaerobic respiration

Answer 29

Using non oxygen molecules
