The image below shows ubiquinone. Shaded in yellow is the isoprenoid side chain, which remainsunchanged during the electron transport chain. Despite this, what function does it serve?CH3(CH₂-CH=C-CH₂) 10-HH3COH3COIDOOCH3--Select one:a. It is hydrophobic, allowing the molecule to be lipid-soluble so that it can diffuse through the membrane between complexe.b. It is hydrophilic, allowing the molecule to be water-soluble and diffuse in the intermembrane space between complexesC. It is hydrophobic, allowing successive molecules to cluster together at complex Id.

According to Paul Boyer, the mechanism of ATP synthesis involves the rotation of the y subunit which in turn causes sequential conformation changes in the aß assemblies. Explain the steps of ATP synthesis according to this mechanism.
You are studying a biochemical pathway that requires ATP as an energy source. To your dismay, the reactions soon stop, partly because the ATP is rapidly used up and partly because an excess of ADP builds up and inhibits the enzymes involved. You are about to give up when the following table from a biochemistry textbook catches your eye. A. ذن فه B. Substrates C. Creatine + ATP ATP + H₂O Pyrophosphate + H₂O Glucose-6-phosphate + H₂O Enzyme A Enzyme B Enzyme C Enzyme D Products Creatine-phosphate + ADP Which of the following reagents is/are most likely to revitalize your reaction? a vast excess of ATP glucose 6-phosphate and enzyme D creatine phosphate and enzyme A D. pyrophosphate ADP + Phosphate 2 Phosphate Glucose + Phosphate AG (kJ/mol) +3 -7.3 -7.0 -3.3
Many processed and fast foods contain trans fatty acids. Explain why these molecules are a problem for the body.
Please state if the statements are true or false. 1. An l-sugar is a sugar where the -OH in the penultimate C is oriented to the left2. The conversion of 1 mole of 1,3-bisphosphoglycerate to 1 mole 3-phosphoglycerate generates 2 moles of ATP
V-class proton pumps run backward relative to the F-class ATP synthase. Consider the cartoon, which shows the conformations of the beta-subunits and ATPIADP + Pj of the F-class synthase. Which of the following associations between the conformation of the beta subunit and ATP/ADP + P¡ is correct for V- Binding Change Mechanism loose binding ADP+P ATP ATP class pumps? C repeat ADP + P, ADP АТР tight binding АТР +P оpen АТР O The open conformation releases ATP. Hydrolysis of ATP to ADP + P¡ drives the change from tight to loose. O Binding of ADP + P¡ drives change from open to loose. Hydrolysis of ATP to ADP + Pj drives the change from open to loose.
Explain which of the following substances ATP, CoA-SH, FAD and NAD+ have the subunits in their structure? A.Have 2 two ribose subunits.
3) The overall reaction for photosynthesis is: 6CO₂ + 6H₂O + ATP C6H₁2O6+ 60₂ (or more accurately 2x C₂H603) a. On this diagram identify where each of these reactants and products are found. b. Why don't you see the water or oxygen in this diagram? C. We can find the electrons from the water on here, where are they?

1. Draw the products that would be produced from phospholipase C cleavage of a glycerophospholipid with a phosphoserine head group, an alpha linoleic acid attached to C2 of the glycerol and a linoleic acid attached to the C3 of glycerol. Draw these products at pH=1. Be sure to number the fatty acid carbons in your products
Why is glucose phosphorylated to become glucose-6-phosphate? Group of answer choices to isomerize it to glucose 1 phosphate to activate the enzyme hexokinase to trap glucose inside the cell and commit it to the pathway to form bisphosphate molecules
guanosine and a water bind in the active site, does not matter in which order. The scissile N-1 glycosidic bond between the anomeric carbon and N9 of the base is broken resulting in an oxocarbenium transition state. The leaving group electrons are not protonated, but instead swing up to form a double bond between N9 and C8. The double bond that is already present on the purine swings out on N7 and is protonated by an active site histidine acting as a general acid. An active site aspartate acts as a general base, and deprotonates the water substrate molecule. The deprotonated water is then free to attack the transition state in a manner that will generate an αribose. Draw the active site and show how the mechanism works. You will need to draw 3 or 4 different active site “snap-shots” to show the entire process. Be sure to clearly show the transition state and how it might be stabilized
What would be the most direct result if NAG (N-acetylglucosamine acid) could not be synthesized? The outer membrane would have nothing to attach to The tetrapeptide chain beneath NAM could not be formed There would be no way to form a dimer with NAM (N-acetylmuramic acid) One of the domains of lipopolysaccharide (LPS) could not be made
