BIO CHEMIST 3053. Biochemistry-Gift-2-Spring-2019. Possible Questions: BLUE Possible Answers: From Previous GIFT: Yellow Highlight Notes: GREEN. Biochemistry 3053 GIFT 2 Possible Questions: BLUE Possible Answers: RED From Previous GIFT: Yellow Highlight Notes: GREEN 1. Which enzyme is considered [REDACTED]? Part of TCA and ETC? FADH2 - ubiquinone oxidoreductase Succinate dehydrogenase Rate limiting: Of glycolysis: phosphofructokinase-1 (stronger) or hexokinase *** hexokinase is important but not rate limiting*** Of TCA: isocitrate dehydrogenase 1. Which enzyme is considered part of TCA and ETC? A. Malate dehydrogenase B. Citrate synthase C. Isocitrate dehydrogenase D. NADH- ubiquinone oxidoreductase E. FADH2- ubiquinone oxidoreductase 2. A solution at pH [REDACTED] contains a weak acid, HA. The pKa of the acid is [REDACTED]. What is the ratio of [A- ]:[HA]? pH=7 pKa=6.5 pH= pka + log ([A- ]/[HA]) 7= 6.5 + log ([A- ]/[HA]) log ([A- ]/[HA])= 0.5 ([A- ]/[HA])= 100.5 = 3.17 1 ratio of [A- ]:[HA]= 3.16:1
