Structure and functions of living organisms - Respiration

Question 1

How does the process of respiration produce ATP in living organisms

Answer 1

the breakdown of glucose into carbon dioxide and water, with the release of energy that is used to produce ATP

Question 2

What does ATP do

Answer 2

Provide energy for the cells

Question 3

What are the differences between aerobic and anaeroebic respiration

Answer 3

Aerobic - Uses oxygen, happens slower, releases more energy (ATP)

Anaerobic - Doesn’t use oxygen, Happens quicker, releases less energy (ATP)

Question 4

What is the word equation and balanced equation for aerobic respiration in living organisms

Answer 4

Glucose + Oxygen ———->
carbon dioxide + water + energy

C6H12O6 + 6O2 —-> 6CO2 + 6H2O
+ energy(ATP)

Question 5

What is the word equation for anaerobic respiration in animals and plants

Answer 5

Glucose —>
ethanol + carbon dioxide + energy
(C2H5OH) (2ATP)

Question 6

Practical: Investigate the evolution of carbon dioxide and hat from respiring seeds or other suitable living organisms
