It’s C. The start point of the cycle. I took this on my test
Answer:
In the genetic code, a stop codon (or termination codon) is a nucleotide triplet within messenger RNA that signals a termination of translation into protein
Explanation:
Proteins are based on polypeptides, which are unique sequences of amino acids. Most codons in messenger RNA (from DNA) correspond to the addition of an amino acid to a growing polypeptide chain, which may ultimately become a protein. Stop codons signal the termination of this process by binding release factors, which cause the ribosomal subunits to disassociate, releasing the amino acid chain. While start codons need nearby sequences or initiation factors to start translation, a stop codon alone is sufficient to initiate termination.
The term is Facilitated diffusion.
Facilitated diffusion is a transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell's energy, and because it does not use the cell's energy, it is a passive transport.
The energy is provided by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell.
The carrier proteins of the GLUT family are responsible for transporting glucose. They bind to glucose , which causes them to change shape to fit in the membrane passage then they translocate the glucose molecule from one side of the membrane to the other.
Red blood cells use facilitated diffusion to absorb glucose.
Answer:
protein - amino acid
Explanation:
Proteins are one of the four major biomolecules in nature. Proteins are polymers of monomeric units called AMINO ACIDS. Amino acids are joined together by a type of covalent bond called PEPTIDE BOND to form proteins. Hence, since proteins are made up of amino acids, the hydrolysis of proteins will result in amino acids.
Hydrolysis is the breaking down of a large polymer into its monomeric unit with the release of water (H2O) molecule as a product. The bonds that forms between the respective amino acids are broken, hence, releasing the amino acids.
