A patient presents with a deficiency of thiamine. If this patient's liver
cells are compared with normal cells, which of the following products
would be decreased in the thiamine-deficient cell (when compared to
the normal cells) if the cells are only given glucose as a fuel?
Give this one a try later!
, Glucagon CO2
H2o Atp

An enzyme is participating in a general acid-base catalysis reaction
with an optimal reaction pH of 6.0. If acid is added to the environment
reducing the pH to 3, what is the likely impact to the rate of reaction?
Give this one a try later!
The rate of reaction is likely to
The enzyme will become denatured
decrease as the pH is out of
and stop functioning
optimal catalytic range
The rate of reaction will increase due The reaction will proceed at the same
to higher acidity rate regardless of ph
