What is the role of NAD+ in cellular respiration? to receive electrons from the citric acid cycle and deliver them to the electron transport chain to catalyze the synthesis of ATP from ADP to accumulate in the mitochondrial intermembrane space to facilitate ATP synthesis to serve as a substrate to bind to acetyl-CoA at the beginning of the citric acid cycle None of the answers are correct. 2. How is the energy from the electron transport chain used most directly? to form the bonds of a water molecule to pump hydrogen ions across the mitochondrial inner membrane into the mitochondrial intermembrane space to join ADP with a phosphate to decompose glucose into pyruvate to rotate ATP synthase 3. In the process of alcoholic fermentation, what causes the liquid to bubble? oxygen carbon dioxide nitrogen alcohol sugar 4. Which molecules transport electrons from the citric acid cycle to the electron transport chain? NADH and FADH2 ATP and ADP GTP and GDP oxaloacetate and citric acid None of the answers are correct. 5. What causes the ATP synthase rotor to spin? the passing of electrons through ATP synthase the movement of protons across the mitochondrial membrane the movement of electrons across the mitochondrial membrane the synthesis of ATP from ADP and a phosphate group None of the answers are correct. 6. Which process provides the energy needed to pump protons across the mitochondrial membrane during oxidative phosphorylation? the transfer of electrons in redox reactions the breakdown of ATP to ADP the rotation of the ATP synthase rotor oxidation of isocitrate None of the answers are correct. 7. Which biochemical process do aerobic respiration, anaerobic respiration and fermentation all have in common? glycolysis citric acid cycle oxidative phosphorylation electron transport chain non-oxygen molecules as final electron acceptors 8. Which process in oxidative phosphorylation releases energy? the transfer of electrons in redox reactions the buildup of H+ ions on one side of the mitochondrial membrane the rotation of the ATP synthase rotor the synthesis of ATP from ADP and a phosphate group All answers are correct. 9. Which of the following atoms has the highest electronegativity? sulfur oxygen hydrogen nitrogen carbon 10. Suppose a microorganism invades a cell, causing damage to ATP synthase. How would cellular respiration be affected? Electrons could not be passed down the electron transport chain. ADP could not be joined with a phosphate to form ATP. Hydrogen ions could not be pumped into the mitochondrial intermembrane space. The cell could not release any energy from the glucose molecule. Glucose could not be broken down into pyruvate. 11. What is the function of oxidation reactions in the citric acid cycle? to catalyze ATP synthesis to release energy from substrate molecules to oxidize NAD+ to NADH to break down glucose into pyruvate All answers are correct. 12. Which statement regarding facultative anaerobes is true? They can survive in the presence or absence of oxygen. They require oxygen to survive. They require the absence of oxygen to survive. They cannot metabolize glucose. They require carbon dioxide to survive.
what is the probability that two cousins who are both carries of a deleterious allele will have a homozygous recessive child with the disease? explain thanks.

Unsaturated fatty acids are often classified according to the number of carbon atoms between the terminal methyl carbon (the omega carbon) and the closest double bond to the methyl end of the chain.
Determine the titer of the original culture.
Consider a mainland-island migration scenario where two alleles are segregating and the observed frequencies of heterozygotes are such that H=.32 for the mainland and H=.5 for the island. (These are the values of heterozygosity) What are Pisland a..
