Pyruvate dehydrogenase complex Newborn screening shows a biotinidase deficiency in a 2-day old infant. This deficienty impairs the infant's ability to reuse and r...

MEDICAL BIOCHEMISTRY FINAL, UNE BIOCHEMISTRY FINAL EXAM /ACTUAL EXAM WITH CORRECT DETAILED AND VERIFIED ANSWERS/A+ GRADE In glycolysis, is considered the committed step in the pathway. - ANSWER PFK-1 Phospholipids are made up of one or more fatty acids, a core, a phosphate, and which one of the following? - ANSWER alcohol

Biochemistry II Exam 1 Questions And Answers A+ Review Solution Homeostasis is the maintenance of a dynamic(not static) steady state in an organism through careful control of biochemical processes. Example is regulation of glycolysis and gluconeogenesis(blood glucose high we want glycolysis to occur and low blood glucose levels we want gluconeogenesis to occur) - ANSWER-Define homeostasis and provide an example of a cellular process that helps maintain homeostasis. oxidative processe...

HMX biochemistry Exam Questions And Answers (Verified And Updated) Activation energy - answerenergy needed to get a reaction started Delta G (change in G - change in free energy) - answerrespresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme - answercatalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition ...

I have no Mitochondria. I can only perform glycolysis to make ATP. What type of cell am I? - Red blood cell (erythrocyte) I have Mitochondria. I can perform glycolysis and oxidative phosphorylation (TCA, ETC). But I do NOT have glycogen stores, I cannot perform FA Oxidation. I can use ketones for energy, but I don't like to. What type of cell am I? - Neuron (brain cell) I can perform glycolysis and oxidative phosphorylation. I have glycogen stores. I can burn Fatty acids for ene...

NADH-Q oxidoreductase - ANSWER-Also known as complex 1 2e - ANSWER-How many electron does NADH donate in complex 1? Succinate-Q reductase - ANSWER-Also known as complex 2 Q-cytochrome C Oxidoreductase - ANSWER-Also known as complex 3 Cytochrome C Oxidase - ANSWER-Also known as complex 4 reduced - ANSWER-Oxygen acts as an electron acceptor and is —- into water therefore it is important that we receive oxygen for it to dissociate into Hydrogen Hydrogen ions - ANSWER-With the in...

Basic (smallest) living unit of the body - Answer Cell Primary Function of Mitochondria - Answer Produce ATP Homeostasis - Answer Maintenance of a constant internal environment during unstressed conditions. Internal environment doesn't always remain absolutely constant. General Components of a Biological Control System - Answer Sensor, Control Center, & Effectors Negative Feedback - Answer change in factor causes reaction to restore previous levels (thermoregulation, glucose, BP) ...

activation energy - energy needed to get a reaction started Delta G (change in G - change in free energy) - respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme - catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition - results in decrease in activity of that enzyme, reaising activation en...
