<h3><u>Answer;</u></h3>
b). Activation of an upstream guanine nucleotide exchange factor
<h3><u>Explanation</u>;</h3>
- <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
- The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.
It is the presence of oxygen-bound hemoglobin that makes it bright red
A ) if it s dna G with C and A with T so if it s C 32 G its 32 you have only 100% so it should be 100-32-32 =36 A=T so 36=A+T 64=2T T =18
