Three proteins present in the blood plasma are: Albumin - help in osmotic balance Globulin - involved in the immune system Fibrinogen -... 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
Some transmembrane proteins form channels to allow ions and polar molecules to travel across the membrane. This type of transport is called... View Article
Transport proteins or transmembrane proteins are the membrane proteins that help in the movement of ions across the hydrophobic lipid bilayer by... View Article
Prions are misfolded or abnormally folded proteins. They have the ability to transmit their misfolded shape to normal proteins and cause fatal... View Article
Protein pumps are transmembrane proteins, which are involved in the active transport of ions across the membrane against the concentration... View Article
Golgi bodies contain different enzymes, which modify proteins it receives from the endoplasmic reticulum. These enzymes are present in the... View Article
The end product of protein digestion is amino acids. Protein is broken down by various proteolytic enzymes in the stomach and duodenum such as... View Article
Proteins are the monomers of amino acids. A protein chain does not exist everywhere as an extended thread, instead, it is folded into secondary... View Article
Proteins are first digested in the stomach by the action of pepsin, which converts proteins into smaller polypeptides. It is secreted by peptic... View Article
Proteins are digested in the stomach and duodenum of the small intestine. The main enzymes that catalyse protein digestion are pepsin secreted in... View Article
Digestion of proteins starts in the stomach with the action of the enzyme pepsin. The peptic or chief cells present in the gastric glands secrete... View Article
The start codon is required at the initiation step. The ribosome subunits bind to mRNA at the start codon, which is AUG. It is recognised by the... View Article
The correct order of stages of translation is initiation, elongation and termination. The first step is the aminoacylation or charging of tRNA.... View Article
