Question
Chapter 35, Problem 2AC
Summary Introduction
To determine:
The initial hopes of scientists when leptin was discovered after they found that excess leptin in blood does not reduce hunger or food intake.
Introduction:
Leptin is a peptide secreted by fat cells, and helps to regulate fat storage in mammals. Leptin secretions increase when fat storage “increases” and “decreases” when fat storage falls down to an optimum level.
Summary Introduction
To suggest:
An evolutionary explanation for leptin’s role in fat regulation.
Introduction:
Leptin is a hormone of energy expenditure; and is formed by adipose cells that help to regulate energy balance by inhibiting hunger.

Pancreatic β cells express a receptor for fatty acids. Fatty acid binding to the protein appears to stimulate insulin secretion. Does this phenomenon make metabolic sense?
In order to normalize blood sugar levels after a meal, mammalian systems release insulin and rely on a different enzyme to phosphorylate glucose after it enters liver cells. Explain the mechanisms by which these two systems decreases blood sugar to safe levels.
Fatty acids from stored triacylglycerols (fat) are not available for gluconeogenesis. Speculate why we do not have the enzymes to directly convert fatty acids into glucose. Plants (especially seeds) do have enzymes to convert fatty acids into carbohydrates. Why are they so lucky?

- Leptin inhibits eating and is secreted in amounts in direct proportion to body fat. Moreover, obese people have normal amounts of leptin and leptin receptor. Why, then, do people become obese?arrow_forwardResearchers investigating the role of fat metabolism in diabetes generated PPAR peroxisome proliferator-activated receptor gamma (PPARγ) knockout mice. When fed a high fat diet, these mice did not gain extra adipose tissue or display significant weight gain. Explain why this is the case.arrow_forwardMammals in the Arctic (e.g., reindeer) have higher levels ofunsaturated fatty acids in their legs than in the rest of theirbodies. Suggest a reason for this phenomenon. Does it have asurvival advantage?arrow_forward

It regulates the opposing pathways of glycolysis and gluconeogenesis by altering levels of fructose 2,6-bisphosphate. If glucagon causes a decrease in fructose 2,6-bisphosphate, how does this increase blood glucose levels? Explain..arrow_forwardYou have the task of producing 3 kilogram of porcine (pig) insulin from pig pancreases to create an emergency stockpile of insulin. You know that a typical adult pig has a 269 gram pancreas and it is possible to produce 15 micromoles of purified insulin from 1 kg of pancreatic tissue. How many fresh pig carcasses would you need to produce 3 kg of insulin?arrow_forward
- The typical human adult uses about 160 g of glucose per day, 120 g of which is used by the brain. The available reserve of glucose (~20 g of circulating glucose and ~190 g of glycogen) is adequate to sustain the individual for about one day. After the reserve has been depleted during starvation, how would the body obtain more glucose?arrow_forwardCan you answer all the parts to following question, true or false: Q23: A: The breakdown of a fatty acid produces more energy than the breakdown of glucose (True or False) B: Acetyl-CoA can be directly converted to pyruvate through the TCA (True or False) C: Glucagon stimulates the liver to store energy by performing glycolysis (True or False) D: The keto diet is dangerous due to the risk of developing ketoacidosis (True or False)arrow_forwardWhen young rats are placed on a completely fat-free diet, they grow poorly, develop a scaly dermatitis, lose hair, and soon die. These symptoms can be prevented if linoleate or plant material is included in the diet. What makes linoleate an essential fatty acid? Animals lack the enzymes required to synthesize long-chain fatty acids with 14 or more carbons. Animals lack the enzymes required to synthesize odd-number fatty acids. Animals lack the enzymes required to synthesize polyunsaturated fatty acids. Animals lack the enzymes required to introduce double bonds into fatty acids beyond the A9 position.arrow_forward
- Avidin, a glycoprotein found in eggs, has a high affinity for biotin. Avidin can bind biotin and prevent its use by the body. How might a diet rich in raw eggs affect fatty acid synthesis? What will be the effect on fatty acid synthesis of a diet rich in cooked eggs? Explain.arrow_forwardAfter a meal that contains carbohydrates, blood glucose levels usually rise gradually as carbohydrates are digested and the resulting monosaccharides are absorbed into the bloodstream. Suppose you run a test on a human with no lactase production. You would provide a dose (e.g., 25 grams) of lactose and measure changes in blood glucose levels over the next three hours. Predict how blood glucose levels would change from fasting to three hours. Justify your response using the results from the above simulation.arrow_forwardDiabetes often results in the production of reduced levels of insulin. Researchers claim that a drug that binds to and blocks the active site of GSK3 might mimic the role of insulin in the pathway shown in Figure 2. Provide reasoning to justify the researchers' claim.arrow_forward
