Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
Answer: A peptide bond
Explanation:
A peptide bond is a type of bond that covalently joins two amino acids to yield a dipeptide. A peptide bond is formed by removal of elements of water from the alpha carboxyl group of one amino acid and the alpha amino group of another amino acid. When two amino acids are joined by a peptide bond, a dipeptide is produced. When three amino acids are joined by two peptide bonds, a tripeptide is produced. When a few amino acids are joined by peptide bonds, an oligopeptide is produced while when many amino acids are joined, the product is called a polypeptide.
Answer:
Enzymes are proteins that are able to increase the rate of a reaction without being consumed by the reaction. They are also called natural catalysts.
Explanation:
Enzymes increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed.
