Enzymes are proteins that act as biological catalysts.
yes, glycerol can be absorbed directly into the blood cells as it has been broken down by the peptidase in the small intestine. It takes three processes till it can reach this point the first process is it is broken down by the enzyemes, next it is broken down in the pancreas by the trpsin and finally it is broken down in the peptidase which is the last process making the food the correct size to enter the blood stream
The rough endoplasmic reticulum is involved in protein synthesis, as it contains ribosomes on its surface that help in the production of proteins. It also plays a role in folding and modifying proteins before they are transported to other cellular locations. Additionally, the rough ER is responsible for quality control, ensuring that only properly folded proteins are sent to their intended destinations.
