What is enzyme specificity?
enzymes can only bind with one substrate
enzymes can be used over and over
enzymes can bind with multiple substrates
enzymes are polar
What do enzymes do to chemical reactions?
slow them down
allow them to take place outside the body
speed them up
denature them
The function of nucleic acids contained in the body is to
directing synthesis of proteins necessary for cell function
producing inorganic molecules needed for cell growth
disrupting mitosis and amino acids
forming a variety of gametes that will pass on information
Which group of molecules are used to make proteins?
carbohydrates
amino acids
lipids
minerals
Which compound lowers the activation energy for a chemical reaction?
carbohydrate
enzyme
lipid
nucleic acid
Which of the following describes monosachharides?
they are responsible for lowering activation energy for chemical reactions
they are simple proteins composed of H, N, and C
they are the main molecule used as fuel for cellular work
they are polymers that are broken down into simpler monomers
When an enzyme seems to be working the best at a given temperature, we call that
the awesome temperature
the optimal temperature
the enzymatic temperature
the chemical temperature
Most enzymes work best at what temperature?
32 degrees F
0 degrees C
98 degrees F
40 degrees F
Which of the following is a plant cell least likely to do with simple sugars
use them for fuel
break them down in to Carbon Dioxide and water
link them together to form proteins
store them in the form of starch
Vegetable oils would be classified in which group?
carbohydrates
lipids
proteins
nucleic acids
What are two types of carbohydrates found in living organisms?
fats and lipids
fatty acids and glycerol
sugars and starches
amino acids and proteins
Glucose is a simple sugar, scientifically that is a
disaccharide
monosaccharide
polysaccharide
bisaccharide
What statement about proteins is NOT correct?
proteins can be broken down and used for energy
proteins can bond together to form simple sugars
protein molecule functions are determined by the shape
proteins are long chains of amino acids
Which polymer contains repeating units known as nucleotides?
hemoglobin
DNA
starch
celluose
When we say water has a high specific heat it means
it takes a lot of energy to change the temperature of the water
it doesn't take much energy to change the temperature of the water
water is great at dissolving substances
water has cohesive properties
Water molecules exhibit cohesion, we see this
when water travels up the stem of a plant
when sugar dissolves in water
when we see surface tension of water
we boil water
The smallest unit of matter is
a cell
an organ
an atom
a compound
What was wrong with Claire the dog?
her pH levels were off
she had a mutation on the active site of her enzyme
she had low enzyme production
they couldn't figure it out
Why is biochemistry important in biology?
because it helps us understand the building blocks of cells
because it helps us understand chemical reactions in cells
because it helps us understand how our bodies work
all of the above
