A risk factor associated with the use of metformin in the treatment of diabetes is lactic acidosis. Acidosis is associated with [a decrease] in blood pH, due to [an increase] in the concentration of hydrogen ions (H+). Given this change in blood pH, hemoglobin is more likely to [release] oxygen. Correct Answer- Acidosis is associated with a decrease in blood pH, due to an increase in the concentration of hydrogen ions (H+). Given this change in blood pH, hemoglobin is more likely to release oxygen. A small segment of Kevin's green opsin gene is shown below. What would be the resulting mRNA sequence? Kevin's opsin gene at nucleotide positions 936 to 941. 5'-G.C.C.T.A.G-3' (coding strand) 3'-C.G.G.A.T.C-5' (template strand) c. 5'-GCCUAG-3' Correct Answer- This sequence is the same as the coding sequence, and the "T" bases have been replaced with "U", as is found in RNA. A substrate binds to an enzyme at a specific site, referred to as a(n)_________________. b. Active site Correct Answer- The active site of an enzyme is the site where the substrate specifically binds to the enzyme and the reaction is carried out. Acetyl-CoA, a central molecule in metabolism, is produced in the mitochondrial matrix. However, it is used for the synthesis of fatty acids in the cytosol. The transport of the acetyl- CoA from the matrix to the cytosol occurs by the conversion of acetyl-CoA to_______________.
