DNA is copied because it cannot fit through the nuclear membrane and travel down to the ribosome.
So it is transcribed (translated) to messenger RNA (mRNA). The mRNA can fit through the nuclear membrane and travel down to the ribosome where proteins can be made.
This is why we cannot send the entire DNA molecule itself, it is simply too big to fit. This is why mRNA is extremely important for amino acid production.
The statement is true. Digestion of food molecules in the digestive system in the gastrointestinal tract does not require coupling of ATP hydrolysis; but instead requires enzymes that speed up the spontaneous reaction. Enzyme digest specific food substrates at different parts of the digestive system until the final useful products of these enzymatic reactions are absorbed to the body metabolism.
Root hair cells. Plants absorb water from the soil by osmosis. ... Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
