Proteins called enzymes are important for us to digest our food. Some people are missing a protein called lactase that breaks down the sugar in milk, lactose. What problems would these people have? A - They would only break down lactose as a source of sugar, but not glucose B - They would break down lactose too rapidly and it would make them sick C - They could not digest lactose and it would make them sick D - They would not digest glucose and it would make them sick

Which of the following statements is true? Multiple Choice   The human body normally uses very little protein for energy.   The body needs protein to make sodium, calcium, and other mineral elements.    Proteins are comprised of smaller chemical units called nucleic acids.   Proteins are comprised of phosphorus, oxygen, hydrogen, and carbon

You were interested to see a human cell under the microscope, so you went to the lab to look for a dye to stain human cells you looked for a stain called Answer: Your friend invited you for dinner, and you were anxious not to gain weight, and you were counting your calorie intake; which of the following dishes would you avoid having since it will have the highest number of calories? 200 grams of fried chicken breast O b. 200 grams of fried beef steak 200 grams of roasted salmon fish O d. 200 grams of black beans 200 grams of roasted chicken breast

When 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.

1.) How do enzymes affect the proteins that we ate? 2.) How can co-enzymes affect enzyme activity?

1. Insulin.....a. Carries glucose into the muscle cellb. signals the muscle cell to take up glucose c. signals the synthesis of glucose in the liver d. carries lactate from the muscle to the liver 2.In the fasting, state, the Liver helps maintain a normal level of blood glucose by: a. Making ketones and storing them for later.b. stopping glycolysis and using alternative fuels for energyc. speeding up glycolysis because it needs energy to make glucose d. Beginning glycogenesis to build up glucose storage

Diet supplementation is over a $133 billion industry. Pick a dietary supplement currently on the market. What claims does it make? How does it claim to work? What research was performed of this supplement?

E. coli brings lactose into its cell by using an enzyme called Lac Permease. Once the lactose is inside, another enzyme called ß-galactosidase converts the lactose into galactose and glucose. 1. How is E. coli's way of dealing with lactose similar to how your cells do it? 2. How is it different?

In the 1930's a chemical known as DNP was touted as en effective diet pill. Weight loss was dramatic in patients taking this drug. However, to quote Efraim Racker (A New Look at Mechanisms in Bioenergetics, Academic Press, 1976, p. 155), ..."the treatment eliminated not only the fat but also the patients,...This discouraged physicians for awhile..." This drug works for weight loss, by causing the leakage of H+ across the inner mitochondrial membrane. Which of the following would you expect to see in patients taking DNP? Select the best answer. Question options:   decreased ability to produce ATP    increased ability to produce ATP   decreased ability to use Krebs cycle to produce ATP   slowing down the citric acid cycle.
