Less energetic electrons. Why are electrons carried by FADH 2 not as energy rich as those carried by NADH? What is the consequence of this difference?
Draw the structure.
Saccharide X occurs in the roots of several species of plants. Deduce the structure of saccharide x from the following data:
1. Acidic hydrolysis of 1 mol of stachyose yields 2 mol of D-galactose, 1 mol of D-glucose, and 1 mol of D-fructose.
2. Stachyose is a nonreducing sugar.
3. Treating stachyose with an a-galactosidase produces a mixture containing D-galactose, sucrose, and a nonreducing trisaccharide called
raffinose.
4. Acidic hydrolysis of raffinose gives D-glucose, D-fructose, and D-galactose. Treating raffinose with an a-galactosidase yields D-galactose
and sucrose. Treating raffinose with invertase (an enzyme that hydrolyzes sucrose) yields fructose and melibiose
5. Methylation of saccharide x followed by hydrolysis yields 2,3,4,6-tetra-O-methyl-D-galactose, 2,3,4-tri-0-methyl-D-galactose,
2,3,4-tri-O-methyl-D-glucose, and 1,3,4,6-tetra-O-methyl-D-fructose.
Just Arrange.
The enzyme serine hydroxymethyltransferase (SHMT) requires pyridoxal phosphate (PLP) as a cofactor.
Arrange the steps of the likely mechanism for SHMT‑catalyzed serine degradation (producing glycine and N5,N10‑methylenetetrahydrofolate)

- Fo-F1 ATPase. The energy for ATP synthesis from ADP and Pi is provided by the downhill transport of protons through the rotary FoF1 ATP synthase (lecture 22). The enzyme has 3 a-b and 12 ‘c’ subunits. The mitochondrion maintains Df=180 mV (negative inside), pHin = 8, pHout=7, [Pi] = 3 mM and ADP is present as well. How much energy is available (from the proton electrochemical gradient) for ATP synthesis under these conditions (in kJ/mol)?

This question is specifically asking for the identification of the biomolecules that are attached to the sphingosine core, then we need to answer what bond causes those biomolecules to be connected to the sphingosine, what reaction created that bond (maybe addition or oxidation etc.), what were the starting materials and lastly what reagents or conditions are needed for the reaction to occur.

ATP synthesis in chloroplasts is usually light dependent; it does not happen in the dark. When researchers shifted isolated chloroplasts from a low pH solution to a more alkaline (higher pH) solution, ATP synthesis occurred even in the absence of light! This was an experiment used to support the chemiosmosis mechanism of ATP formation in chloroplasts. Why? What would happen if the isolated chloroplasts were shifted to a lower pH solution? What would be the results if the above experiments were performed in the presence of light? If these experiments were performed in mitochondria instead of chloroplasts, what results would we expect?arrow_forward
