C1.2 - Cell respiration

Question 1

ATP structure

Answer 1

RNA nucleotide
Five carbon sugar ribose
Adenine
Phosphate group
Universal energy currency

Question 2

what is ATP used for?

Answer 2

whenever cellular process requires energy
Active transport
Anabolism
Movement

Question 3

hydrolysis

Answer 3

Chemical reaction where a water molecule is used to break down large molecules

Question 4

exergonic reaction

Answer 4

Spontaneous reactions where energy is released into surrounding environment

Question 5

endergonic reaction

Answer 5

Non-spontaneous reactions were an energy is absorbed from surrounding environment

Question 6

Phosphorylation

Answer 6

Process of adding a phosphate group to a molecule often to transfer energy

Question 7

respiratory substrate

Answer 7

Any molecule that can be broken down in respiration to release energy, e.g. glucose

Question 8

Aerobic respiration

Answer 8

with oxygen
Happens in the cytoplasm and mitochondria
Uses all respiratory substrate
Has a high ATP yield
Carbon dioxide and water are waste products

Question 9

anaerobic respiration

Answer 9

Without oxygen
Happens in the cytoplasm
Carbs are the only respiratory substrate
Has a low ATP yield
Lactic acid is a waste product

Question 10

Variables affecting the rate of cell respiration

Answer 10

temperature
PH
Oxygen concentration
