14-2. Explain whether the following statements are true or false. Justify the false ones.A. Many, but not all, of the electron transfer reactions involve metal ions.B. The electron transport chain generates an electrical potential across the membrane because it moves electrons from the intermembrane space into the mitochondrial matrix.C. The proton electrochemical gradient consists of two components: a difference in pH and an electrical potential.D. Ubiquinone and cytochrome c are both electron carriers that are easily diffused.E. Plants have chloroplasts and therefore can live without mitochondria.F. Both chlorophyll and the heme group consist of a system of double bonds that allow it to absorb visible light.G. The role of chlorophyll in photosynthesis is equivalent to that of the heme group in the mitochondrial electron transport chain.H. Much of the dry weight of a tree comes from the minerals it takes from the ground at its root.

BIOC 384 Glycolytic Pathway Q9.2:  What is the total number of moles of ATP generated per mole of glucose in the glycolytic pathway and which enzymatic reactions generate these ATP molecules?  Why are these reactions called "substrate level phosphorylation" reactions?

q/5

Q29. FADH2 is similar to NADH in that it is also oxidized by the respiratory electron transport chain. However, oxidation of FADH2 does not yield as much ATP as the oxidation of NADH. Why doesn't oxidation of FADH2 generate as much ATP as oxidation of NADH?   A. Energy is more spread out in FADH2. B. FADH2 has fewer C-H bonds than NADH. C. FADH2 oxidation occurs at complex II; it therefore bypasses the proton-pumping of Complex I. D. FADH2 oxidation to FAD releases fewer electrons than the oxidation of NADH to NAD+.

Please help with this practice question. I am not sure what the answer is. I believe it would be NAD+ and NADH production, but I am not sure.

C7 Q8:

Question: Role of the triacyl glycerol cycle.  Summarize the cycle referring to Figure 19.9. What role does the cycle play in metabolism? Here are some infromation:  Metabolic integration within the human body depends on the redistribution of metabolites, ions, and hormones by the circulatory system. This complex network consists of ∼150,000 km of blood vessels (from major veins and arteries to microcapillaries) that recycle 6 L of blood every minute throughout the body. The circulatory system links together the major tissues and organs of the body in such a way that biochemical pathways in different cells share metabolites, ensuring that the metabolic efficiency of the whole organism is greater than the sum of its parts. This process of maintaining optimal metabolite concentrations and managing chemical energy reserves in tissues is called metabolic homeostasis. This term describes steady-state conditions that apply to a wide variety of physiologic parameters. Metabolic homeostasis is…
