Detailed explanation-1: -Glucose is a carbohydrate, a monosaccharide. Glucose does not contain amino acids whereas proteins contain amino acids. Thus, the energy provider is not a function of proteins. Hence, the correct option is the option (D) As energy provider for metabolism.
Detailed explanation-2: -The endoplasmic reticulum (ER) plays a key role in the modification of proteins and the synthesis of lipids. It consists of a network of membranous tubules and flattened sacs.
Detailed explanation-3: -The mRNA produced enters the cytosol where translation happens. This process does not directly lead to protein synthesis.
Detailed explanation-4: -The synthesis of proteins and lipids takes place in the endoplasmic reticulum. It is of two types-smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER). The lipid synthesis occurs in the smooth endoplasmic reticulum (SER).
