The graph below represents the effect of enzyme concentration on the reaction rate.

Based on this graph, what can you conclude about the relationship between enzyme concentration and the rate of starch chemical reaction? (ASK 1a1)(DOK1)

Question 4 options:

a. The reaction rate decreases as the enzyme concentration increases


b. The reaction rate increases as the enzyme concentration decreases


c. The reaction rate increases as the enzyme concentration increases


d. The reaction rate is indirectly proportional to the enzyme concentration

Answers

Answer:

C

Explanation:

Increasing enzyme concentration will speed up the rate of a reaction, as long as there is substrate available to bind to.

Rate of reaction is directly proportional to the enzyme and substrate concentration. Therefore, option (C) is correct.

What is enzyme- substrate complex ?

An enzyme-substrate complex is what happens when a substrate attaches to an enzyme's active site during a chemical process. Aspects including temperature, pH, co-factors, activators, and inhibitors can affect an enzyme's activity.

A substrate is placed into the active site of the enzyme, or the location where weak bonds can form between two molecules. An enzyme substrate complex is created, and the enzyme's pressures on the substrate cause it to react and turn into the reaction's intended product.

Therefore, option (C) is the correct option as long as there's enough substrate for enzyme to bind and convert to product.

Answers

Giraffes and Elephants: Giraffes have adapted a long neck over time letting them eat and access food allowing them to survive. If a dry season was unusually long they would succeed fine because they are able to eat and drink from the trees. Elephants have survived with similar tactics of eating higher up, they have rough skin allowing them to outlast the heat, and only need water after long periods of time.
