Energy transfer in and between organisms

Question 1

What does life depend on?

Answer 1

A continuous transfer of energy

Question 2

In photosynthesis, light is absorbed by chlorophyll and this is linked to what?

Answer 2

The production of ATP

Question 3

What is linked to the production of ATP in respiration?

Answer 3

In respiration various substances are used as respiratory substrates. The hydrolysis of these respiratory substrates is linked to the production of ATP

Question 4

How does the production of ATP occur in both respiration and photosynthesis?

Answer 4

Occurs when protons diffuse down an electrochemical gradient through molecules if the enzyme synthesis, embedded in the membranes of cellular organelles

Question 5

What provides indirect evidence for evolution?

Answer 5

The fact that the process of photosynthesis is common in all photoautotrophic organisms and the process of respiration in common in all organisms

Question 6

In communities, biological molecules produced by photosynthesis are consumed by what and what are some of these used as?

Answer 6

other organisms, including animals, bacteria and fungi

- Respiratory substrates by the consumers

Question 7

Are photosynthesis and respiration 100% efficient?

Answer 7

NO

Question 8

What is also not efficient?

Answer 8

The transfer of biomass and its stored chemical energy in a community from one organism to a consumer
