Question

Chapter 27, Problem 17P

Interpretation Introduction

(a)

Interpretation:

The metabolite in the given case should be determined.

Concept Introduction:

A metabolite is that the intermediate consequence of metabolism. The term substance is typically restricted to tiny molecules.

Interpretation Introduction

(b)

Interpretation:

Defending predictions about Malonyl-CoA as a key indicator of nutrient availability.

Concept Introduction:

Malonyl-CoA could be a extremely regulated molecule in carboxylic acid synthesis; intrinsically, it inhibits the rate-limiting step in beta-oxidation of fatty acids. Malonyl CoA inhibits fatty acids from associating with carnitine by regulation the protein carnitine acyl transferase, thereby preventing them from coming into the mitochondria, wherever carboxylic acid chemical reaction and degradation occur.

Examine the metabolic pathway. The enzymes that catalyze each step are identified as "e" with a numeric subscript. e₁ e3 e4 A B с 1° B' 02 e5 e6 e7 E F Which enzymes catalyze irreversible reactions? ப e ez ☐ ez e4 ☐ ப es 26 5 e7 Which of the enzymes is likely to be the allosteric enzyme that controls the synthesis of G? €2 ез e4 es 26 5 e7

An allosteric enzyme that follows the concerted model has an allosteric coefficient (T/R) of 300 in the absence of substrate. Suppose that a mutation reversed the ratio. Select the effects this mutation will have on the relationship between the rate of the reaction (V) and substrate concentration, [S]. ㅁㅁㅁ The enzyme would likely follow Michaelis-Menten kinetics. The plot of V versus [S] would be sigmoidal. The enzyme would mostly be in the T form. The plot of V versus [S] would be hyperbolic. The enzyme would be more active.

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as ẞ-lactamase), an enzyme present in some penicillin-resistant bacteria. The mass of this enzyme in Staphylococcus aureus is 29.6 kDa. The amount of penicillin hydrolyzed in 1 minute in a 10.0 mL. solution containing 1.00 x 10 g of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change appreciably during the assay. Plots of V versus [S] and 1/V versus 1/[S] for these data are shown.
