Chapter 10 Cellular respiration

Question 1

cellular repiration

Answer 1

Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

Question 2

ATP

Answer 2

(adenosine triphosphate) main energy source that cells use for most of their work

Question 3

What type of process is cellular respiration?

Answer 3

Chemical process

Question 4

What are the types of cellular respiration

Answer 4

aerobic and anaerobic

Question 5

Down sides of anaerobic respiration

Answer 5

Very inefficient

Question 6

Chloroplast vs Mitochondria

Answer 6

chloroplast are found in only plant cells along with mitochondrion, which differs from mitochondria which is found in only animal cells

Question 7

Stroma vs Matrix

Answer 7

They are both the cytoplasm of the energy related organelles

Question 8

Cristae

Answer 8

Infoldings of the inner membrane of a mitochondrion that houses the electon transport chain and the enzyme catalyzing the synthesis of ATP.

Question 9

Thylakoids vs Cristae

Answer 9

they are both double lipid bi-layer

Question 10

Cellular respiration vs breahing

Answer 10

Breathing is physical exchange of gasses. Respiration is a chemical process

Question 11

Hydrolysis

Answer 11

Breaking down complex molecules by the chemical addition of water

Question 12

calorie

Answer 12

Amount of energy needed to raise temperature 1 gram of water 1 degree C

Question 13

Calorie vs calorie

Answer 13

A Calorie (also known as a food calorie) is the amount of energy needed to raise the temperature of water by 1 kg@ A calorie (also known as a chemistry calorie) is the amount of energy needed to raise the temperature of water by 1g

Question 14

How is E stored in cells

Answer 14

It is stored in the bods of macromolecules

Question 15

1g of glucose

Answer 15

3811 calories

Question 16

1g of Fat

Answer 16

8893 calories

Question 17

Do cells break down glucose fast or gradually?

Answer 17

Gradually to avoid loss of energy. If broken down quickly energy would be lost as heat or light.

Question 18

general equation for cellular respiration

Answer 18

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP energy

Question 19

Glycolysis

Answer 19

the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Question 20

Krebs cycle

Answer 20

second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions

Question 21

electron transport chain

Answer 21

A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP.

Question 22

Where does glycolysis occur?

Answer 22

cytoplasm

Question 23

Where does the Krebs cycle occur?

Answer 23

mitochondrial matrix

Question 24

Where does the electron transport chain occur?

Answer 24

inner membrane of mitochondria

Question 25

alcholic fermentation

Answer 25

The process by which yeast turns sugar into carbon dioxide (CO2) and alcohol.

Question 26

lactic acid fermentation

Answer 26

the chemical breakdown of carbohydrates that produces lactic acid as the main end product
