The enzyme penicillinase in certain bacteria is used to decompose penicillin and render it inactive. The Michaelis-Menten constants for this enzyme and substrate are K_M = 5.0 × 10⁻⁵M⁻¹ and k₂ = 2.0 ×10³ s⁻¹. (a) What is the maximum rate of decomposition of penicillin if the enzyme concentration is 4.9× 10⁻⁷M? (b) At what substrate concentration will the rate of decomposition be half that determined in (a)?

(a) ____ × 10^ _____ M s⁻¹

(b) ____ × 10^ _____ M

Seven tomato plants were treated with chlorogenic acid (and seven control plants were not treated) to determine if this acid influences the activity of the enzyme o-diphenol oxidase in their leaves which is normally 13 units. The enzyme activity data are presented below. Does this treatment affect enzyme activity?

Imagine that you are observing an enzyme-catalyzed reaction in the laboratory. The reaction is progressing as expected. As you periodically add more enzyme, the reaction increases proportionally until suddenly it stops increasing. At this point, no matter how much more enzyme that you add, the reaction rate does not change. Assuming no other chemicals have been added or changed, explain why the reaction rate has leveled off.

Amino Industries common shares sell for $100 per share. Amino expects to set their next annual dividend at $4.00 per share. If Amino expects future dividends to grow at 5 percent per year, indefinitely, the current risk-free rate is 2 percent, the expected rate on the market is 7 percent, and the stock has a beta of 1.5, what should be the best estimate of the firm's cost of equity?

Multiple Choice

• 18.50 percent

• 13.25 percent

• 9.25 percent

• 7.27 percent

Unsaturated fatty acids are (more or less) oxidied than saturated acids. Which yields more energy?

How is acetyl-Coa used in liver cells? in what process/ what does it produce

Ebola virus is a virus that is frequently and rapidly lethal in humans. The envelopes around particles of Ebola virus are studded with a viral glycoprotein (GP). Researchers hypothesized that, to enter a human cell, GP molecules must be cleaved by a protease enzyme, after which they bind with a protein called NPC1 in the human cell membrane. Reptile cells do not normally express the NPC1 protein, but the researchers modified some reptile cells to express NPC1. They then exposed the unmodified and modified cells to Ebola virus, both in the presence of a protease inhibitor that prevents GP cleavage, and without that inhibitor present. They then measured the frequency at which Ebola viruses infected the cells. These treatments are summarized below. I. Unmodified reptile cells, protease inhibitor absent II. Unmodified reptile cells, protease inhibitor present III. Modified reptile cells, protease inhibitor absent IV. Modified reptile cells, protease inhibitor present V. Unmodified human cells, protease inhibitor absent Of the following, which is a correct reason for including group V? :

(A) If the virus cannot enter group V but can enter group III, it shows that GP cleavage is not necessary for infection.

(B) If the virus can enter group V but cannot enter group IV, it shows that NPC1 is necessary for infection.

(C) If the virus can enter group V but cannot enter groups I, II, III, or IV, it shows that both GP cleavage and NPC1 are necessary for infection.

(D) Group V is a positive control.
