Why is the muscle pathway more efficient than the yeast pathway?

Lactic acid converted back into pyruvate when oxygen is available.

400

What part of the cell does the formation of pyruvate take place?

cytoplasm

Compare aerobic respiration and anaerobic respiration. (5 marks)

Aerobic respriation - requires oxygen, 36 ATP, mitochondira, produce water 

Anaerobic respiration - no oxygen required, 2 ATP, cytoplasm, produce lactic acid and ethanol Both - produce CO2, use glucose, produce pyruvate

What is the net energy yield from glycolysis for one glucose molecule?

2 ATP

200

The process the produces the greatest amount of ATP during respiration is    ???

oxidative phosphorylation

Compare chemiosmosis in photosynthesis and respiration (5 marks).

Photosynthesis - H pumped into thylakoid space, ATP energy source for Calvin Cycle (produce sugar), Chloroplast Respiration - H pumped into inter-membrane space, ATP energy for metabolic activity, mitochondria Both - ATP synthase, H pumped from low conc. to high conc

What are the products of photolysis?

H ions, electrons, oxygen gas

Distinguish between action spectrum and absorption spectrum.

Absorption spectrum shows how much of a particular wavelength is absorbed by the pigments. Action spectrum shows how much photosynthesis takes place at a particular wavelength.

400

Draw 3 graphs to represent the 3 limiting factors of photosynthesis.

Light, CO2, Temperature

I have an aquatic plant. How could I measure the rate of photosynthesis (3 marks).

Directly - oxygen bubbles, control time, count bubbles. Or use an oxygen sensor. Indirectly - measure the pH (acidity) of the water as an indicator of CO2. (Or directly with a CO2 sensor).
