The storage polysaccharide starch is a mixture of the molecules amylose (an unbranched polymer of glucose) and amylopectin (a branched polymer of glucose). Both amylose and amylopectin only have one reducing end, but amylopectin has many nonreducing ends.Enzymes that break down these molecules act on the nonreducing ends. Briefly describe why this is advantageous.
a. Draw b furanose
b. A polysaccharide which is a major constituent in the exoskeleton of arthropods and the cell walls of fungi.
c. D-allose is C-3 (Carbon-3) epimer of D- glucose. DRAW D- allose

- In the cytosol, the fatty acid C16:0 is desaturated by the Δ6 fatty acyl-CoA desaturase. The resulting fatty acid then goes through one round of elongation. What will be the product of this process? a) C18:1 cis-Δ8 b) C14:1 cis-Δ4 c) C18:1 cis-Δ6 d) C16:1 cis-Δ6arrow_forwardFatty acid chains after subjected to degradative enzymes in the intestines are hydrolyzed (hydrolysis) into 2 Carbon acetic acid fragments (Each fragment becomes an acetyl Co-A molecule). What stage of cellular respiration will this product of lipolysis enter? How many ATP can one fragment produce in cellular respiration?arrow_forwardAlthough rabbits cannot digest the cellulose in their all-plant diet, bacteria that live in their cecum can. However, to make full use of the nutrients released by bacterial action, a rabbit must produce and eat a special type of feces. Why must the rabbit reswallow this material to obtain the nutrients released by bacterial action?Some people who have gallstones experience pain after they eat, with fatty meals causing the greatest discomfort. Why do such meals trigger gallbladder pain? Diabetes insipidus is a medical disorder in which a person produces an unusually large amount of highly dilute urine. Some cases are caused by a gene mutation, but in most people, diabetes insipidus arises after a head injury. Explain how an injury to the head could affect kidney function.Marine mammals and desert rodents both have highly efficient kidneys that produce only a tiny amount of very concentrated urine. What selective pressure shaped this trait in both animals?arrow_forward
- The teenager had intense running exercise causing conversion of sugar to pyruvate to lactate. The cramping is due to the accumulation of lactic acid in the muscles cells resulting in decreased intracellular pH.

The growing fatty acid chain is elongated by the sequential addition of two-carbon units. C. The process is repeated 7 times to produce palmitate. D. The process occurs in the cytosol.arrow_forwardIn a healthy nursing human infant, which of the following sugar(s) would be found in the small intestine just prior to absorption across the intestinal luminal epithelial cells?

- You are a liver cell and have just been given 1 million C25:0 fatty acid molecules (Note: These fatty acids have 25 carbons each). Are you, as a liver cell, able to generate net production of glucose from these C25:0 fatty acids? If so, how can you use these C25:0 fatty acids to generate glucose? If not, explain why you are not able to do so?arrow_forwardFatty 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?arrow_forwardCarnitine shuttle is used to Transport FA chains from the adipose tissue to the liver. Transport FA chains from the blood-stream to the cytosol.
