- Biochemistry question. Please help with. Thanks in advance For each of the enzymes listed below, explain what the enzyme does including function, names (or structures) of the substrate and products and the pathway(s) (if applicable) it is/are found in. (a) ATP synthetase (b) succinate dehydrogenase (c) isocitrate lyase (d) acetyl CoA carboxylase (e) isocitrate dehydrogenase (f) malate dehydrogenasearrow_forwardDraw and name each alcohol and classify it as primary, secondary, or tertiary. Explain your answer thoroughly.arrow_forwardDraw the product of each reaction. If there are multiple products, draw only the major product. Explain your answer thoroughly.arrow_forward
- Identify the type of bond in the following disaccharides. Number your carbons to show work. Explain your answer thoroughly. Draw the number of carbons also.arrow_forwardDraw and explain your answer thoroughly: a. What is the molar mass of aspirin (C9H8O4)?b. What is the mass of 0.00225mol of aspirin?c. How many moles of aspirin are present in 500mg of aspirin?arrow_forwardGeranylgeranyl pyrophosphate 5 is converted by general acid-base catalysis to 6, and then to the natural product 7. For clarity only limited atom numbers are shown, but the main chain carbons are numbered 1 to 16, and the off-chain methyl substituents are numbered 17-20. A. Based on what you specified in A, use curly arrows on the drawing above to convert 5 to 6, and 6 to 7. Invoke general acids and general bases as needed, and draw in hydrogens as necessary . B. On the structure of 7, write in the atom numbers for the carbons marked with an asteriskarrow_forward
- α-Pinene (4) is synthesized enzymatically from nerol pyrophosphate 1. Drawn an arrow-pushing mechanism from 1 to 2 to 3 to 4; add explicit hydrogens to clarify, if needed.arrow_forwardA reverse phase column chromatography separates proteins according to their polarity. Which pentapeptide will be eluted FIRST when chromatographed at pH 7 using a reverse phase column such as a C-18 column? Peptide Sequence (from N-terminal to C-terminal) AKGED GAAVF ALLLI MCYAG GAAVF MCYAG ALLLI AKGEDarrow_forwardMelting of three DNA samples with varying lengths was monitored by increase of ultraviolet light absorbance at 260 nm. Which is the shortest DNA? A B Carrow_forward
- Select the CORRECT description of the peptide bond. The peptide bond can freely rotate around the peptide bond. The peptide bond is non-polar, hydrophobic and does not have a dipole. The peptide bond is most stable in the cis configuration. The peptide bond is rigid and planar. The peptide bond has a mix of single and double bond characters. The peptide bond is most stable in the trans configuration.arrow_forwardBelow is a fractional saturation curve for O2 binding to adult hemoglobin. Assume that curve Y represents a system at pH 7.4 and with a normal physiological level of 2,3-BPG. Curve Z represents a system that ___________________ Curve Z: is at pH 7.4 with a higher than normal physiological level of 2,3-BPG. is at pH 7.4 with a normal physiological level of 2,3-BPG but with a decreased level of CO2. has a higher pH with a normal physiological level of 2,3-BPG. has a higher pH with a lower than physiological level of 2,3-BPG.arrow_forwardWhich is a homotropic positive effector of aspartate transcarbamoylase (ATCase)? oxygen CTP aspartate ATParrow_forward
