The best answer is B - Proteins.
Proteins make up enzymes, or to put it another way enzymes are made up of protein. It is enzymes that speed up the chemical reactions. Enzymes are organic catalysts, substances that speed up a (biochemical) reaction but do not take part in the reaction and remain unchanged at the end of the reaction.
In man, there are many enzymes. The majority of these are found in the digestive system where they greatly aid the process of food breakdown from complex molecules to simple molecules. Examples include salivary amylase found in saliva, which begins the gradual breaking down of starch into glucose right from the moment food is placed in the mouth and mixed with saliva. Pepsin in the stomach breaks down protein.
1 wait what 2 i think A or D
Your correct answer would be yes because the transcript is constantly increasing
Because particles move randomly, molecules tend to move
across the membrane in both directions. Yes, the model indicates that the molecules are moving
in equal amounts in both directions. This calld the state of equilibrium where
the forward and backward movements are equal hence the net movement is equal to zero
