1In order to form a polymer from monomers, monomers must:
- Aundergo trypsin reactions
- Bundergo dehydration reactions
- Cundergo amylase reactions
2Which of the following cellular functions is associated with the smooth endoplasmic reticulum (SER)?
- Ahouses the DNA
- Bproduces hydrogen peroxide as byproduct
- Ccontains hydrolytic (digestive) enzymes
- Dstores Ca 2+
- Eenergy powerhouse of cell (makes ATP)
3Which of the following statements is false regarding protein structure?
- Aone type of secondary structure found in proteins is called an alpha helix
- Bbeta sheets are an example of tertiary structure
- Ctertiary structure may be supported with hydrogen bonding, ionic bonding , hydrophobic interactions and covalent bonding amino acids in the polypeptide
4Which of the following membrane proteins are involved in active transport across the plasma membrane?
- Aa chloride channel
- Bsodium/potassium ATPase (Na+/K+pump)
- Cglucose transporter
5What will happen to a red blood cell that is placed into a hypertonic solution?
- Anothing, it will remain unchanged, the water will flow in an dout of the cell at the same rate
- Bit will lyse (burst) because too much water will enter the cell from the surrounding fluid
- Cit will shrivel because too much water will leave the cell into the surrounding fluid
6The molecule DNA is important to biological systems because
- Ait can be replicated
- Bit forms a complex, double-helical structure.
- Cnucleotides form genes.
