A reactant involed in an enzyme catalyzed reaction is called
An enzyme ___ the rate of a chemical reaction by ___ the activation energy for the reaction.
increases, decreasing
An enzyme causes the affect described in #3 by binding to the substate(s) at a region called the ___. This destabilizes the chemical bonds in the substate(s) and positions the substate molecule(s) in a manner that favors a reaction.
How does increasing the temperature effect an enzyme catalyzed reaction?
It increases the rate of the reaction until it peaks at an optimal temperature; then the rate rapidly slows until the reaction stops
A(n) ___ is an organic molecule that aids an enzyme catalyzed reaction by removing one of the products or bringing in one of the starting molecules.
A substance which speeds up a chemical reaction but is not used up in the reaction is a(n)___.
A(n) ___is a substance binds to an enzyme, either preventing the enzyme from binding to the substrate(either by blocking the active site or changing the shape of the enzyme.) This prevents the enzyme from speeding up the chemical reaction.
This biochemical pathway is used to release the chemical-bond energy of molecules such as carbohydrates to produce ATP. All organisms must be able to do this to survive.
Cellular respiration
Organisms such as green plants and algae capture solar energy and store the energy in the chemical bonds of carbohydrates. This is called:
The light reactions of photosynthesis occure in the ___ of the chloroplast.
thylakoids (grana)
During the light reactions, ___ is (are) converted to___.
solar energy, ATP and NADPH
The light-independent reactions of photosynthesis (the Calvin cycle) occure in the ___ of the chloroplast.
During the Calvin cycle, ___ is (are) converted to ___.
ATP and NADPH, carbohydrates
The energy captured by photosystem (PS) II is passed to an electron transport system and used to produce____.
The electrons lost by PS II in the process above must be replaced oxidizing ___, in the process, ___ is produced.
water, oxygen
The energy captured by PS I is passed to an enzyme and used to produce___.
