Aresearcher claims that increasing temperature by 10 degrees will double the rate of an enzyme-catalyzed reaction. to test this, he designed an experiment. for each tube, the researcher will measure the rate of product formation

which best justifies the inclusion of tube 5 as a control?

it will provide a measurement of product formation in the absence of the substrate

it will provide a measurement of product formation in the presence of a denatured enzyme

it will show the effect of doubling the amount of substrate on the rate of product formation

it will show the effect of increased enzyme activity on the rate of product formation

It will provide a measurement of product formation in the presence of a denatured enzyme

Explanation:

For any experimental research study, it is a common practice to have sets of experimental runs as well as a control. The main essence of the control is to investigate the effects of a given substance such as an enzyme on the experimental conditions. This is done by comparing the experimental results in the presence of an enzyme with the results in the absence of an enzyme.

ill try to . no promises tho.

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
