B9 Aerobic and Anaerobic respiration

Question 1

fact about aerobic respiration

Answer 1

it takes place all the time in plant and animal cells

Question 2

what does aerobic respiration react with

Answer 2

glucose reacts with oxygen
-transfers energy that your cells use

Question 3

whats produced from aerobic respiration

Answer 3

carbon dioxide and water

Question 4

why is it called aerobic respiration

Answer 4

it uses oxygen from the air

Question 5

what type of reaction is it and why

Answer 5

an exothermic reaction

-it transfers energy to the environment-more energy transferred when new bonds are formed in products

Question 6

aerobic respiration equation

Answer 6

glucose + oxygen - carbon dioxide + water

Question 7

where does aerobic respiration take place

Answer 7

in the mitochondria

Question 8

what is a cytoplasm

Answer 8

where enzymes are made. location of reactions in anaerobic respiration

Question 9

what is a nucleus

Answer 9

holds genetic code for enzymes for aerobic respiration

Question 10

what is mitochondrion

Answer 10

contain the enzymes for aerobic respiration

Question 11

what is cell membrane

Answer 11

allows gases and water to pass freely into and out of the cell. controls the passage of other molecules

Question 12

name 4 needs for respiration

Answer 12

-living cells need energy to carry out the basic functions of life
-in animals energy from respiration is transferred to make muscles contract
-mammals and birds maintain a constant internal body temperature
-

Question 13

What is oxygen debt?

Answer 13

The amount of oxygen needed to break down lactic acid which has built up.

Question 14

anaerobic respiration takes place

Answer 14

without oxygen

Question 15

why is anaerobic respiration not as efficent as aerobic respiration

Answer 15

glucose molecules arent borken down completely

-animal cells the end product of anaerobic respirations lactic acid instead of carbon dioxide and wtaer

Question 16

why is less energy transferred during anaerobic

Answer 16

the breakdown of glucose is incomplete,

Question 17

anaerobic respiration word equation

Answer 17

glucose———- lactic acid (energy transferred to the environment)

Question 18

anaerobic respiration in yeast cells is named what

Answer 18

-fermentation

Question 19

state the word equation for anaerobic respiration in plants and yeast cells

Answer 19

glucose——– ethanol + carbon dioxide

Question 20

is respiration an exothermic or endothermic reaction

Answer 20

exothermic
-because it involves the release of energy

Question 21

what type of respiration releases more energy and why

Answer 21

-aerobic respiration
-this is because it doesn’t break down the glucose molecule completely so doesnt release as much energy

Question 22

what can the ethanol produced by aerobic respiration be used for

Answer 22

making alcoholic drinks

Question 23

Body Responses to Exercise

Answer 23

Increase in heart/breathing rate and in breath volume
Glycogen stores in the muscles are converted to glucose for cellular respiration
Flow of oxygenated blood to muscles increases

This happens to increase the rate of supply of glucose and oxygen and removal of carbon dioxide.

Question 24

Anaerobic respiration in plant cells

Answer 24

Production of Ethanol and Carbon Dioxide.

Question 25

What is Metabolism?

Answer 25

-the sum of all reactions in the body, including conversion of glucose to starch, glycogen and cellulose, formation of lipid molecules,

Question 26

What does blood flowing through the muscles do during anaerobic respiration?

Answer 26

Transports lactic acid to liver where it is converted to glucose.
