Biomass is defined as:

the organic material derived from plant and animal material

produced in anaerobic fermentation

is measured numerically and is objective

Sources of biomass include

plant oils, rice, wood chips, Chemistry textbooks

A non-competitive inhibitor would

have a complementary shape to the allosteric site

A permanent change to the active site of an enzyme

Why is rubisco a dufus?

not a very specific active site

11
Sources of biomass include
plant oils, rice, wood chips
tyres, oils, organic garbage
plastic bags, sugar cane, old cars
Chemistry textbooks
12
A non-competitive inhibitor would
have the same shape as the active site
have a similar shape to the active site
have a complementary shape to the allosteric site
have a similar shape to the allosteric site
13
Glyphosate
forms a prosthetic group
is an inhibitor
is a cofactor
Is a cycling coenzyme
14
What is denaturing

A change to the shape of the substrate
A temporary change to the active site of an enzyme
A change to the active site of a substrate
15
Why is rubisco a dufus?
warmer temperatures increase specificity
oxygen can bind to the allosteric site
it likes to mix things up
not a very specific active site
16
Which is correct of collision theory in enzymes
No energy is needed to break a substrate apart
Cold temperatures have a higher rate of collisions
Optimal pH is always 7
Enzymes (active site) must collide with substrates to react
