Question

Identify for the items listed below whether they are characteristics/structures found in eukaryotes (E), prokaryotes (p), both eukaryotes and prokaryotes (B), or neither (N). Exocytose RNA chromosome Intermediate filaments Membrane-bound organelles 708 ribosome's Mitosis Nucleus Microtubules RNA processing Chloroplast For each of the following statement answer with a "S" if the statement is true of simple diffusion; with a" F" if it is true of facilitated diffusion; with an " A "if it is true of active transport; and with a " N "id it is not true for any means of transport. Any, all, or none of the choices may be correct for a given statement. Requires a carrier molecule localized within the membrane. Depends primarily on the solubility properties of the substance. Sensitive to metabolic poisons. Transport occur along the gradient but may be regulated by mechanosensitive channels. Transport occurs against the gradient of concentration. Transport may be dependent on ATP hydrolysis. Transport can occur against a gradient of electrical potential. Multiple Choice. Choose the answer that best completes the statement or answer the question. Write your answer to the left of the question. An enzyme decreases the rate of a reaction. binds substrates in a manner that facilitates the formation of product. changes the position of the equilibrium of the reaction. does not change the rate at which the equilibrium is achieved. may drive an endergonic reaction. The site on an enzyme that will bind the substrate is called the prosthetic group. catalyst. active site. metastable site. activation site.

Explanation / Answer

Answer:

Eukaryotes

Prokaryotes

Both

Neither

Exocytosis

Intermediate filaments

Nucleus

RNA processing

1. F

2. S

3. A

4. N

5. A

7. N

lll.

i). E. May drive an endergonic reaction

ATP uses free energy created by hydrolysis to drive endergonic reactions through phosphorylation.

ii). C. Active site

An active site contains a binding site that binds the substrate and orients it for catalysis.
