Deedra's dad has Alzheimer's Disease (AD) which is caused by a change in protein structure - -True Alzheimer's disease is caused by aggregation of the Amyloid beta peptide and tangle formation by the tau protein. What kinds of amino acids are likely to drive the formation of these protein aggregates? - -hydrophobic After learning about Alzheimer's disease and one of the drugs used in its treatment, what other drug design strategies could you use to offer treatment for AD? - -1. Drugs th...

What vitamin does not travel through the bloodstream in the form of a lipid micelle? - -Vitamin C Which lipid has a 4-ring structure? - -Sterol Which of the following situations is MOST likely to increase the rate of beta oxidation? - -fasting A patient who is on a no-fat diet is at particular risk of deficiency in: - -Vitamin A During starvation, triglycerides can help supply some of the body's glucose needs. Which breakdown product of triglycerides can be used to make glucose? - -glycero...

The polysaccharide cellulose is composed of sugar monomers linked through beta linkages, with their CH2OH groups in opposite direction relative to the neighboring monomer. - -True Nutrient that can not be broken down to a substance that can participate in the production of ATP via aerobic cellular metabolism - -Vitamin E Glycolysis produces 2 ATP molecules, through what process are these ATP molecules made? - - Substrate level phosphorylation What product of beta oxidation is able to enter...

Hb (hemoglobin) binds to CO (carbon monoxide) with a higher affinity than oxygen and stabilizes the R (relaxed) state - -True When hemoglobin changes from the T to the R, it has a high affinity for oxygen - -True When hemoglobin changes from the R to T, it has a low affinity for oxygen - -True Cooperatively refers to - -structural changes that increases the affinity for oxygen in hemoglobin When the oxygen concentration is high, the heme shape is planar. When the oxygen concentration is lo...

DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands - -true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? - -RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as frameshift mutations, incl...
