AQA A2 Biology Photosythesis, Respiration and ATP (chapter 2, 3 and 4)
Define energy:
Why are the units of
energy?
What does the body
need
energy for?
How does energy flow through living systems?
Word equation for then hydrolysis of ATP
Decribe how ATP is converted into ADP and ADP is converted into ATP
Name the three types of phosphorylation
How are leaves adapted for photosynthesis
General equation for photosynthesis
How are the chloroplasts structured?
What occurs wen chlorophyll absorb light?
When the chlorophyll loses electrons is it oxidised or reduced?
How does the excitation of chlorophyll lead to ATP production?
How is reduced NADP produced in the light dependent reaction?
Equation for the photolysis of water:
Why is the photolysis of water needed during the light dependant reaction?
Where does the light dependant reaction take place?
How are the thylakoids adapted for their function (light dependant reaction)?
How does carbon dioxide enter the chloroplast?
How is carbon dioxide used to produce organic molecules (glucose) and regereratec RuBP in the calvin cycle
where does the light independent reaction take place?
why does the light independent reaction not take place in the absence of light
what is the law of limiting factors
what are two ways of measuring the rate of photosynthesis
if light intensity is the limiting factor how is it related to the rate of photosynthesis
what is the compensation point
how does carbon dioxide concentration affect the rate of photosynthesis
how does temperature affect the rate of photosynthesis
how and why is glucose phosphorylated
how does phosphorylated glucose two molecules of pyruvate
how are two molecules of reduced NAD produced
why is the overall ATP yield only 2
where does glycolysis take place
why is glycolysis the only source of atp in the absence of oxygen (anaerobic conditions)
give the equation for the link reaction
explain how the link reaction produces 2 molecules of carbon dioxide
how does the krebs cycle produce to reduced hydron carriers and atp
what is the overall yield for the link reaction and krebs cycle for one molecule of glucose
explain the significance of the krebs cycle
why are hydrogen acceptors oxidised where do the protons and electrons
how is the energy lost at each electron acceptor used
how is an electrochemical gradient established
how does protons moving back into the matrix produce atp
what is the name of the process which generates atp
how is water produced in the electron transport chain
why is oxygen described as the final proton accepter in the electron transport chain
what process can occur in anaerobic conditions
what is the equation for anaerobic respiration in plants and some microbe?
how is ethanol produced from pyruvate in plants and some microbes
What is the equation for anaerobic respiration in animals?
How is lactate produced from pyruvate in animals?
Why is lactate build up bad in humans?
What is the energy yield from aerobic respiration?
