Photosynthesis pre-quiz Flashcards
What is the equation for photosynthesis?
water + carbon dioxide –> G3P + oxygen
Why do enzymes function at a specific pH?
because enzyme active sites contain specific amino acids that are sensitive to changes in pH
The delta H for an instant cold pack is 24.5 kJ. Is this:
1) in equilibrium
2) endergonic
3) a redox reaction
4) exergonic
endergonic
Where do allosteric regulators bind?
binds to the enzyme outside of the active site
How can enzyme activity be increased?
increasing the reaction temperature
In which compartment of the plant cell do the light-independent reactions of photosynthesis take place?
in the stroma
What is a transition state?
the complex formed as covalent bonds are being broken and re-formed during a reaction
Where do competitive inhibitors bind?
to the active site to prevent the reaction from occurring
In a chemical reaction:
1) the rate depends on the activation energy
2) the activation energy is a negative value if the reaction is spontaneous
3) the rate depends on the value of Gibbs free energy
4) the activation energy depends on the value of Gibbs free energy

Which of the following is a catabolic process?
1) product of lipids in the endoplasmic reticulum
2) dissolving sugar in water
3) synthesis of proteins from amino acids
4) digestion of sucrose
