Proteins and Carbohydrates are both
Polymers or large molecules made up of smaller subunits (monomers)
Made of sugars (glucose)
Lipids of large molecules
Nucleotides of DNA
Which biomolecule is properly matched to its monomer?
Nucleic acid: amino acid
Protein (polypeptide):fatty acids
Lipid: Nucleotide
carbohydrate: monosaccharide (glucose)
Which of the following is the function of nucleic acids?
Serve as energy storage
Serve as the primary unit of cell membranes
Store and transmit genetic information
Serve as biological catalysts
One function of lipids is to store energy. What is another function of lipids in the human body?
To form plasma (cell) membranes
To make energy from the sun
To control chemical reactions
To provide quick energy for the cell
The molecule in the diagram plays what role in the body?
Releasing energy
Storing fat
Forming the structure of nucleic acids like DNA
Controlling blood glucose levels
Line B in the graph represents a reaction with an enzyme added. How did the enzyme affect the reaction?
Increase the activation energy
Increased the energy change
Lowered the energy change
Lowered the activation energy
Which statement is a valid (true) conclusion based on the graph shown? (Make sure you can support your answer from the graph).
Temperature can affect the rate of reaction of an enzyme
The maximum (highest) rate of respiration is at 57 degrees
Growth can be controlled by enzymes
The maximum (greatest) rate of digestion is at 45 degrees
What is the function of carbohydrates?
Provide long term energy storage
Store genetic information
Provide fast, short term energy storage
Build structure and makes enzymes
What do carbohydrates and lipids have in common?
They both store energy
They both store genetic information
They both are involved in building structures such as bones and muscles
They both speed up chemical reactions
All the following are true about enzymes EXCEPT...
They reduce the amount of energy needed for a chemical reaction so it occurs faster
Enzymes are proteins
Enzymes usually end with "ase"
Enzymes store the genetic code
