Carbon cycle 2.0

Question 1

Relationship between photosynthesis and cellular respiration (including the equations)

Answer 1

Product of one’s process is the reactant of another

Cellular respiration: Glucose + oxygen –> CO2 + water
PHS: CO2 + water -(sunlight)–> Glucose + oxygen

Question 2

Explain/ describe the process of cellular respiration & photosynthesis

Answer 2

• Cellular respiration carried out by all organisms release CO2 into the atmosphere
• Photosynthesis removes CO2 from the atmosphere to form carbon-containing molecules in green plants

Question 3

Effects of a high concentration of CO2 in the atmosphere

Answer 3

• GHGs such as CO2 trap heat in the atmosphere
• Build up of GHGs may lead to global warming/ extreme climate
  > which is an increase in the avg. temp. of the earth’s atmosphere

Question 4

Effect of enzymes in PHS

Answer 4

• Made of proteins
• Present in the chloroplast of plants
• Speed up the rate or reaction on the process of PHS

Question 5

Definition of ATP and word equation for the transfer of chemical energy from plants to animals

Answer 5

ATP - molecule for storing and transferring energy in cells

Glucose + Oxygen –> CO2 + Water + chemical energy in the form of ATP

Question 6

What do you call a horizontal line in a graph

Answer 6

[…] eventually ~plateaus~ as […]

Question 7

What do you call enzymes which don’t function anymore (or have died)

Answer 7

Denatured (possibly due to high temp.)
