Question 0

What is LF

Answer 0

Determines R of P
Least favourable condition
Change others : no effect

Question 1

How to figure out order of Calvins

Answer 1

Algae grown under light; in thin transparent cuticle
Algae had radioactive 14C
Photosynthesising algae dropped into hot methanol
(stops chemical reaction immed. Enzymes denatured)
Compounds in algae separated ; 2 way chromatography
Radioactive compounds discovered and order they were produced

Question 2

Degree C - Too hot

Answer 2

Effects Enzyme activity - RUBISCO & RUBPASE in LIR

Denaturation 
3D structure breaks 
Bonds broken 
AS shape change 
AS & substrate change shape; no longer complimentary

Question 3

Degree C - Too cold

Answer 3

Effects Enzyme activity - RUBISCO & RUBPASE in LIR

AE not reached
Less collisions
Less kinetic energy
Less successful complexes formed

Question 4

C02

Answer 4

NO LIR 
No carbon fixation 
NO GP, No TP
NO organic prods 
Less RUBP

Question 5

☀️ Intensity

Answer 5

No LDR
No LDR products ; ATP & NADPH
No LIR

When light is LF ; R of P = DP
