Updated
What is the cell theory? - ANSWER-1. cells are the basic unit of life 2. All living things
are made up of cells 3. all cells come from pre--existing cells.
What would be the effect of increasing the pH of a solution from pH4.0 to pH9.0 on the
rate of a reaction paralyzed by an enzyme which has an optimum pH of 7.0? -
ANSWER-The rate would increase and then decrease
Which phrase best describes enzyme substrate specificity? - ANSWER-The enzyme
has an active site that only one specific substrate can bind to
which molecule is a monosaccharide? - ANSWER-glucose
What is the role of a carbohydrates in animal cells? - ANSWER-energy
What features are correct for hydrogen bonding? - ANSWER-it is involved in the
cohesion of water and it results in the thermal properties of water
What best describes the tertiary structure of a protein? - ANSWER-interactions forming
hydrogen bonds between the amino acids
What is true about enzymes? - ANSWER-They lower the energy of activation for a
reaction
The part of the enzyme where the substrate binds is knows as the... - ANSWER-active
site
When the temperature of an enzyme controlled reaction was increased from 15 C to 30
C the reaction rate also increased. Why? - ANSWER-The enzymes have more kinetic
energy so collide with more substrate molecules
What is not a primary function of protein molecules? - ANSWER-energy storage
What can reduce the effect of a competitive inhibitor of an enzyme? - ANSWER-
increase the substrate concentration
which of the following could cause denaturation of an enzyme? - ANSWER-high
temperature
