Why do plants need to have a higher rate of respiration over photosynthesis?
More ATP is produced in respiration than photosynthesis. Plants use more ATP than is produced during photosynthesis.
1 of 9
Which two processes occur in the mitochondrial matrix?
Link Reaction and Krebs Cycle.
2 of 9
What are the products of glycolysis?
2ATP + 2pyruvate + 2NADH
3 of 9
What are the products of the link reaction?
2acetylCoA + 2CO(2) + 2NADH
4 of 9
Explain why ATP is useful in many biological processes. (4marks)
Energy is released in small amounts. Broken down in one single, simple step. Phosphorylates substances, making them more reactive. Can be reformed.
5 of 9
Why is glucose not used as a respiratory substrate for isolated mitochondria?
Glucose is broken down in the cytoplasm during glycolysis. Glucose can't cross mitochondrial membranes.
6 of 9
Describe the part played by the inner membrane of a mitochondrion in producing ATP.
Energy is transferred down the electron transport chain which provides energy provides energy to take protons (H+) into the intermembrane space. Protons then move back in through ATP Synthase. Energy combines ADP + Pi.
7 of 9
Humans synthesise more than their body mass of ATP each day. Explain why this is necessary.
ATP is released in small amounts at a time. ATP can't be stored.
8 of 9
In which steps is carbon dioxide produced?
