Review 2.9 Photosynthesis
Review 8.1 Metabolism
Essential idea: Light energy is converted into chemical energy.
These videos provide an overview of the topic
02 Photosynthesis (HD).m4vThe chloroplast
The chloroplast
S1: Annotation of a diagram to indicate the adaptations of a chloroplast to its function.
U14: The structure of the chloroplast is adapted to its function in photosynthesis.
Exercise 1: Complete the Quizlet learn exercise below.
The light dependent reaction
The light dependent reaction
U1: Light-dependent reactions take place in the thylakoid membranes and the space inside them.
U3: Reduced NADP and ATP are produced in the light-dependent reactions.
U4: Absorption of light by photosystems generates excited electrons.
U5: Photolysis of water generates electrons for use in the light-dependent reactions.
U6: Transfer of excited electrons occurs between carriers in thylakoid membranes.
U7: Excited electrons from Photosystem II are used to contribute to generate a proton gradient.
U8: ATP synthase in thylakoids generates ATP using the proton gradient.
U9: Excited electrons from Photosystem I are used to reduce NADP.
Exercise 2: Use a flowchart and diagrams to explain the light dependent reactions of photosynthesis
calvins experiments
calvins experiments
NoS: Developments in scientific research follow improvements in apparatus—sources of 14C and autoradiography enabled Calvin to elucidate the pathways of carbon fixation. (1.8)
A1: Calvin’s experiment to elucidate the carboxylation of RuBP.
Exercise 3: Watch this video and outline Calvin's experiments that discovered the light independent reactions.
The light independent reaction
The light independent reaction
U2: Light-independent reactions take place in the stroma.
U10: In the light-independent reactions a carboxylase catalyses the carboxylation of ribulose bisphosphate.
U11: Glycerate 3-phosphate is reduced to triose phosphate using reduced NADP and ATP.
U12: Triose phosphate is used to regenerate RuBP and produce carbohydrates.
U13: Ribulose bisphosphate is reformed using ATP.
Exercise 4: Use a flowchart and diagrams to explain the light dependent reactions of photosynthesis
