Active transport driven directly or indirectly by metabolic energy
The rate-limiting step for the secretion of secretory proteins or the appearance at the plasma membrane for membrane protein is generally thought to be the rate of exit from the ER. Biosynthesis in or at the ER, including folding, modifications, and assembly, hence is the most crucial step for efficient secretion.
Answer:
Diffusion
Explanation:
Diffusion is the process whereby molecules move from an area of high to low concentration
Teens need protein for many reasons like repairing muscles, hair and skin health, etc.
Proteins also help with building enzymes, hormones and vitamins, especially important for adolescents. Proteins are made up of amino acids, most of which your body can naturally produce, h<span>owever, there are nine essential amino acids that your body cannot make, but that you can get through foods you eat. </span>
Answer:
False
Explanation:
Transfer RNA (tRNA) is a molecule synthesized from the process of transcribing DNA into segments located in specific regions of chromosomes. It is involved with protein synthesis in the mechanism of gene translation. This molecule is responsible for driving amino acids to form the polypeptide chains that make up proteins. While it is true that a cell has extensive regulatory systems to prevent the attachment of an incorrect amino acid to a tRNA, it is not true that the attachment of an incorrect amino acid is impossible, although rare, can happen.
