Through the action of Antidiuretic hormone on blood vessels and kidneys, it assists in controlling blood pressure. Most importantly, it is... View Article
Maintaining electrolyte balance and regulation of fluids are carried out by three hormones - Aldosterone - released by the adrenal cortex... View Article
The Antidiuretic hormone (ADH), is a chemical produced in the brain. It helps regulate blood pressure by its action on the blood vessels and... View Article
Digestion begins in the mouth and is completed in the small intestine. The inner lining of the small intestine is richly supplied with villi.... View Article
Membrane proteins may be peripheral or integral proteins. Peripheral proteins are present on the surface of the membrane and are generally... View Article
Facilitated diffusion is a type of passive transport of ions and molecules across the plasma membrane through transmembrane proteins. It does not... View Article
Ribosomes are protein machinery and are present in the cytoplasm freely as well as bound to the membrane of the rough endoplasmic reticulum.... View Article
Carbohydrates, fats and proteins in the food are utilised to get the energy to carry out various metabolic and physical processes. The actual... View Article
Molecules need carrier protein to cross the plasma membrane barrier, which facilitates diffusion down the concentration gradient. Substances... View Article
Proteins, which remain in the cytosol or have to be incorporated into mitochondria, nucleus, chloroplasts, etc. are synthesised by free... View Article
Aquaporin is a transmembrane protein, which regulates the flow of water. It is a type of channel protein and allows a rapid flow of water by... View Article

Proteins are digested in the stomach and small intestine (duodenum) by various proteolytic enzymes such as pepsin, trypsin, chymotrypsin,... View Article
Proteins and carbohydrates are different biomolecules. Proteins are made up of amino acids, whereas carbohydrates contain carbon, hydrogen and... View Article
Small amount of protein may be present in the urine but a large amount of protein is an indication of kidney disease. Protein may leak into urine... View Article
Protein synthesis is an endergonic process as it requires energy. Energy to drive the process is derived from the hydrolysis of ATP and GTP. The... View Article
Yes, transmembrane proteins are involved in the movement of ions and molecules across the plasma membrane through facilitated diffusion and... View Article
Deoxyribonucleic acid (DNA) stores the genetic information and directs the protein synthesis by the cells. The sequence of nucleotides in the DNA... View Article
Some carrier proteins facilitate active transport against the concentration gradient. They utilise the energy released by ATP hydrolysis to drive... View Article
