What shows a decrease in entropy?

The general idea here is that entropy increases as disorder and randomness increase. Similarly, entropy decreases as disorder and randomness decrease. So right from the start, you know that any reaction that has a gas as a reactant and a liquid as a product, for example, will result in a decrease in entropy.

Which reaction would cause a decrease in entropy?

In an endothermic reaction, the external entropy (entropy of the surroundings) decreases.

In which example is entropy decreasing?


Which of the following types of reactions would decrease the entropy within a cell group of answer choices?

Anabolic reactions decrease the entropy within a cell because forming large structures diminish the number of small molecules, this gives order to the cell and results in a decrease of the entropy.

Which of these is a correct description of a coupled reaction?

Which of these is a correct description of a coupled reaction? In a coupled reaction, an exergonic reaction provides energy to run an endergonic reaction. The reaction is endergonic.

What will most likely change when an enzyme is added to a reaction?

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Which of the following is an example of an endergonic reaction?

Examples of endergonic reactions include endothermic reactions, such as photosynthesis and the melting of ice into liquid water.

Which is a true statement about the relationship of pH and enzyme action?

All enzymes work best at a neutral pH. Adding more acid does not affect the rate of activity of an enzyme. Enzymes function only in a pH range of 4.0 to 5.5. The activity of an enzyme is affected by pH.

How do pH and temperature affect enzymatic action?

Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate. Temperature: Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. Extreme pH values can cause enzymes to denature.

What is the optimal pH for catalase activity?

approximately 7

How does low pH affect enzyme activity?

When the pH value deviates from the ideal conditions, the activity of the enzyme slows down and then stops. The enzyme has an active site at the substrate binding site, and the shape of the active site will change with the change of pH value.

What are the two different types of enzyme inhibitors?

There are two types of inhibitors; competitive and noncompetitive inhibitors. Competitive inhibitors bind to the active site of the enzyme and prevent substrate from binding. They can be, however, dissociated with the addition of more substrates.

What type of enzyme inhibitor is penicillin?

enzyme transpeptidase

What do you mean by enzyme inhibitors?

Enzyme inhibition refers to a decrease in enzyme-related processes, enzyme production, or enzyme activity. A number of clinically important interactions between drugs result from CYP450 inhibition. CYP450 inhibitors are different in their selectivity toward enzymes and are classified by their mechanisms of action.

What type of enzyme inhibition can be reversed?

In reversible inhibition an enzyme is not permanently inhibited or damaged. The inhibition can be reversed when the inhibitor is removed. There are two different types of reversible inhibition: Competitive inhibition: in competitive inhibition the inhibitor is very similar in shape to the normal substrate.
