Question 5

Where does respiration take place in plants ?

Answer 5

Respiration occurs in all the cells of plants .

Question 6

Photosynthesis is the process that provides plants with the enegry they need for life processes , true or false .

Answer 6

False it is respiration that does that .

Question 7

Digestion is the process that provides animals with energy for growth and movement . True of false

Answer 7

FALSE digestion breaks down food , it is respiration .

Question 8

Oxyegn is essential for the life process all living organisms , T OR F

Answer 8

False , only for some organisms , some can respire anerobically (which dosen’t require oxygen )

Question 9

Question 11

What kind of reaction is Aerobic Respiration ?

Answer 11

It is an exothermic reaction .

Question 12

Meaning of exothermic reaction

Answer 12

Transfers energy to the environment

Question 13

Meaning of endothermic reaction

Answer 13

Takes in energy from the surroundings .

Question 14

What is ATP

Answer 14

It is how energy is stored for later use in the body .

Question 15

How are photosynthesis and aerobic respiration linked ?

Answer 15

Aerboic respiration works in the opposite way of photosynthesis

Question 16

Link photosynthess and respiration in pllants

Answer 16

PLants produce food byphotosynthesis anf through respiration release energy through it .

Question 17

What is Anaerobic Respiration

Answer 17

Anaerobic respiration is the process of creting energy without the presence of oxygen .

Question 18

What are two problems iwth anaerobic respiration ?

Answer 18

1. Transfers less energy due to incomplete breakdown of glucose .
2. Lactic acid is a mild poison and a build up of it in the bo yd cuases the muscles to stop working and causes msucle craps .

Question 22

Where does anaerobic respiration occur ?

Answer 22

It occurs in the cytoplasm .

Question 23

What is oxygen debt ?

Answer 23

The amount of oxygen required to breakdown lactic acid into cabron dioxide and water .

Question 24

What is the word equationf or anaerbouc respiration in plants and some microorganisms?

Answer 24

Glucose arrow carbondioxide +Ethanol +Energy transferred to the environment .

Question 25

What is it called when it happens in yeast

Answer 25

Fermentation

Question 26

What is oxygen debt ?

Answer 26

The amount of extra oxygen the body needs after exercise to deal with the accumulated Lactic acid .
