17. There are several types of enzyme regulators that act as either positive or negative controls. Which type of regulator is this an example of: Enzyme 1 Positive or negative: regulator Substrate

help with question 5 please

Predict the substrate and the activity (function) for a and b. For c and d, indicate the type of activity (class of enzyme) only. a) Maltase = b) Alcohol dehydrogenase c) CO2 H2C C. CH3 H3C H- H-N- CH- H,O H,N CH- OH CH CH, d) H,N CH OH

Briefly describe the major difference between the "lock and key" enzyme model and the "induced fit" enzyme model.

According to the following graph, the activity of the enzyme decreases more sharply at high temperature than at low temperature. What are the reasons for this observation? Enzyme activity Optimum temperature Temperature, °C I. As temperature is increased, the substrate binding slowly becomes poorer. II. As temperature is decreased, the enzyme moves more slowly and so reacts more slowly. III. At higher temperatures, the enzyme is denatured and stops working entirely. IV. Temperature has no effect on enzyme activity. ○ I only O IV only I and III O II and III

How does the metal ion in carboxypeptidase A increase the enzyme’s catalytic activit

Questions #58 and #59 please

Show chemical structures for treatment and their mechanism of action for a defective enzyme: Glucose-6-phosphate dehydrogenase.

The following graph is showing the effect of catalyzed reaction. Rate of reaction A enzyme concentration substrate concentration pH temperature B on the rate of an enzyme

The lock and key model and the induced fit model are two models of enzyme action explaining both the specificity and the catalytic activity of enzymes. Indicate whether each statement is part of the lock and key model, the induced fit model, or is common to both models. Lock and key model Induced fit model Common to both models Answer Bank The substrate binds to the enzyme at the active site, forming an enzyme-substrate complex. The substrate binds to the enzyme through noncovalent interactions. The enzyme conformation changes when it binds the substrate so that the active site fits the substrate. The enzyme active site has a rigid structure complementary to that of the substrate.
