(a)
Interpretation:
The effect of cholesterol feeding on the amount of HMG-CoA reductase mRNA should be determined.
Concept introduction:
Cholesterol is an organic lipid molecule. It is a steroid which is synthesized in all animal cells and is an important component of cell membrane. Cholesterol also functions to serve as a precursor for steroid hormones, vitamin D, and bile acid. In vertebrates, cholesterol is produced by the hepatic cells.
(b)
Interpretation:
The purpose isolating actin mRNA must be determined.

- Calculate the number of ATP produced from oxidation of 1 molecule of glucosearrow_forwardExample 1: 1. Suppose an enzyme (MW = 5,000 g/mole) has a concentration of 0.05 mg/L. If the kcat is 1 x 10 s, what is the theoretical maximum reaction velocity for the enzyme? A) 1050 µM/s. B) 100 µM/s. C) 150 μM/s. D) 105 μM/s.arrow_forwardIn 1956, E. P. Kennedy and S. B. Weiss published their study of membrane lipid phosphatidylcholine (lecithin) synthesis in rat liver. Their hypothesis was that phosphocholine joined with some cellular component to yield lecithin. In an earlier experiment, incubating 32 P-labeled phosphocholine at physiological temperature (37 °C) with broken cells from rat liver yielded labeled lecithin. This became their assay for the enzymes involved in lecithin synthesis. Determine the optimal pH for this enzyme and characterize the enzyme activity at different pH values. -O-P-O-CH2-CH₁₂-N(CH3)3 Phosphocholine H₂C-O-C-R HC-O-C-R2 + + + Cell fraction + ? HC-O-P-O-CH₁₂-CH₂-N(CH), O Phosphatidylcholine The researchers then centrifuged the broken cell preparation to separate the membranes from the soluble proteins. They tested three preparations: whole extract, membranes, and soluble proteins. Table 1 summarizes the results.

- Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?arrow_forwardShow work. don't give Ai generated solution....give correct solutionarrow_forwardBiochemistry What is the process of "transamination" in either the muscles or the liver, that involves keto acid or glutamic acid?

- Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)arrow_forwardBiochemistry Please help.
