The rate of a reaction catalyzed by an enzymes usually ________ with temperature; however, at temperatures above the optimum ran
oksano4ka [1.4K]

Answer:

increases; protein denaturation occurs

Explanation:

One of the characteristic of enzymes is the sensitivity to temperature .

Enzymes are sensitive to the changes in the environmental temperature.The enzymatic activities increases with increase in temperature,up to the optimum of 37 degrees in most animals.

However,once the optimum temperature has been exceeded,enzyme activities drops.This is because below optimum the rate of collision between the enzyme active sites and substrate molecules is very high,therefore more products are formed which increases the rate of reactions.

At temperature above the optimum,the high temperature  breaks the bonds,especially the hydrogen bonds holding the 3D structure of the active sites.Therefore,substrate molecules can not fit into the active site,and therefore enzymatic actives of the enzyme is affected,and the enzyme is said to be  denatured

lukranit [14]

Answer:

TCTAGGA

Explanation:

The deoxyribonucleic acid (DNA) molecule consists of two single-strands, which are composed of four different types of nucleotide bases: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). These two DNA strands run in an anti-parallel direction to each other. According to the base-pairing rules, Adenine always pairs with Thymine, while Guanine always pairs with Cytosine. In DNA, Thymine and Adenine form two hydrogen bonds between them, while Guanine and Cytosine form three hydrogen bonds between them.

WILL GIVE THE BRAINLEST <br><br>Explain why the answer you chose is correct.​
Mademuasel [1]

For one thing based off of process of elimination we know that both plant and animal cells have a cell membrane, and a nucleus. Therefore we are left with cytoplasm and cell wall. According to the question we are most likely looking for something in the animal or plant cell that they don’t have in common with each other. Therefore, the answer is cell wall because an animal cell doesn’t have a cell wall, but a plant cell does. The cell wall can also make it more rigid!
