Choose the CORRECT statement about enzymes below. Group of answer choices

Enzymes raise the activation energy needed in a chemical reaction

Enzymes slow down the rate of chemical reactions

Enzymes function best at specific pH and temperatures

Enzymes are carbohydrates and store short term energy

Enzymes function best at specific pH and temperatures.

Explanation:

An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.

Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.

Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

a adaptation is when organism changes itself to fit the environment

ex. when its cold outside i wear a jacket

hello everyone my name is nevaeh, i know everyone needs in some way, shape, or form and i am willing to provide. i set up a google classroom where people can ask me questions and get on work. no question is a stupid question so do not be afraid to ask. i usually only focus on core subjects but if you ask i will with other specialized subjects. i can do essays all the way to power points : )

my google classroom is the code is 7hr2k4

~ use this opportunity to get more so you can thrive in the classroom
