Rat heart muscle operating aerobically fills more than 90% of its ATP needs by oxidative phosphorylation. If each gram of tissue consumes O2 at the rate of 12.0 micromol/min, with glucose as the fuel source.
(a) Calculate the rate at which the heart muscle consumes glucose and produces ATP.
(b) Consider an alternate scenario – what would be the rate of consumption if the energy source was a solely triglycerides whose fatty acyl chains were each 14-C in length and saturated? (Assume the O2 consumption rate remains at 12.0 micromol/min)
(c) For a steady-state concentration of ATP of 6.0 micromol/g of heart muscle tissue, calculate the time required (in seconds) to completely turn over the cellular pool of ATP if glucose us used as the sole fuel source. What does this result indicate about the need for tight regulation of ATP production? (Note: Concentrations are expressed as micromoles per gram of muscle tissue because the tissue is mostly water.)
Determin the respiratory exchange ratio of
C18H36O2(s) + 26O2(g) → 18CO2(g) + 18H2O(l)
Cells maintain different steady state ratios of NAD+/NADH (1000) and NADP+/NADPH (0.01).
(a) How do these ratios relate to the metabolic functions of NAD+ and NADPH?
(b) Given these physiological ratios, what is the AG for NAD+ to oxidize NADPH?
(c) This reaction does not happen in most tissues. Make a hypothesis: what prevents this from
occuring?

- Hypothetical scenerio: When the membrane potential is 80mV across the digestive vacuoles (DV), inside positive, the Vmax for VF-6-2 efflux is 15pmol/h. However, when the membrane potential is 80mV inside negative, the Vmax of VF-6-2 efflux drops to near zero. Researchers suggest an H+ P-type ATPase is also in the membrane and is required for VF-6-2 efflux. Do these data support their suggestion? What type of transporter might PfCRT be?

- Animals often face trade-offs, and one of the goals of modernphysiology is to understand mechanistically why improvementof performance in one way may degrade performance in otherways. In freshwater fish, explain why O2 uptake and Ca2+ uptakeprobably cannot be simultaneously maximized. In other words,why is there a trade-off between the ability to take up O2 and theability to take up Ca2+?arrow_forwardMAKE CONNECTIONS Step 3 in Figure 9.9 is a major pointof regulation of glycolysis. The enzyme phosphofructokinaseis allosterically regulated by ATP and related molecules (seeConcept 8.5). Considering the overall result of glycolysis,would you expect ATP to inhibit or stimulate activity of thisenzyme? Explain. (Hint: Make sure you consider the role of ATPas an allosteric regulator, not as a substrate of the enzyme.)arrow_forwardFrom these data, is the energy solely from the H+ concentration gradient sufficient to generate ATP from ADP and Pi?

- Can I get this rewritten While the surface area of an organism scales as a square of the length (L^2) and the volume of an organism increases as the cube of the length (V^3), basal metabolic rate is not affected by the ratio of surface area to length of an organism.This can be seen in the data extracted from the ADW Quardvaark database as well which showed that mammals had an R^2 value of 0.7258 when looking at their length and basal metabolic rate and an R^2 value of 0.0074 when looking at the length of mammals and their length-specific basal metabolic rate.
