The amount of cholesterol in cell membranes varies from ~40% of lipids in the ______________ membrane to ~10% of lipids in the __________________ membranes correct answers The amount of cholesterol in cell membranes varies from ~40% of lipids in the plasma membrane to ~10% of lipids in the endoplasmic reticulum membranes What do high local concentrations of cholesterol do to phospholipids and membrane fluidity? correct answers prevent lateral movement of phospholipids and decrease membrane fl...

ACS Biochemistry EXAM QUESTIONS AND CORRECT DETAILED ANSWERS | EVERYTHING YOU NEED TO PASS Membrane lipids: phospholipids - ANSWER-Two classes: glycerophospholipids (aka phosphoglycerides) and sphingolipids. Both contain two non-polar tails, a platform they are linked to, and a phosphate-containing polar head group. Phosphoglycerides - ANSWER-class of phospholipids that have two fatty acid chains bound to the alcohol groups in glycerol, with the third alcohol group being bound to amino alcoho...

Which one of the following is involved in the breakdown of glycogen? correct answers inorganic phosphate Which enzyme catalyzes the formation of alpha(1,6) linkages during glycogen synthesis? correct answers branching enzyme The activation of glycogen phosphorylase will lead to a(n) ____ in blood glucose concentrations and is stimulated by the hormone _____. correct answers increase; glucagon Because muscles lack receptors for glucagon, what hormone activates muscle glycogen phosphoryla...

The hydrophilic domain of glycerophospholipids consist of phosphodiester bridges that link the hydrophobic domain to the hydroxyl group of one of these except; Tyrosine Serine Inositol Choline These phospholipids are asymmetrically concentrated in the inner membrae leaet except; Phosphatidylcholine Phosphatidylinositol Phosphatidylethanolamine Phosphatidylserine 1 / 1 pts Question 3 Phospholipids in bile help to solubilize cholesterol and minimize the precipitation of cholesterol and ...

Glycerophospholipids (GPLs): - amphipathic (having both hydrophilic and hydrophobic parts) are main lipid constituent of PM Contain glycerol backbone: 2 fatty acid tails in ester linkage A polar head group (that varies in size) A phosphate ester of another alcohol (choline, ethanolamine, serine, or inositol) GPLs can differ in polar head group, chain length, and saturation of bonds Common cell structures called organelles are either membrane bound or non membrane bound. Choose the follow...

what are membrane functions? correct answers 1) separate cells from the external medium to create an intracellular environment of unique and defined composition 2) allow selective transport of substrates in and out of the cell 3) provide a location for specialized pathways and processes (energy conversion of mitochondria) 4) rapid changes in electric potential across the membranes of neurons as basis of the nervous system 5) localization of receptors to facilitate response to physiological s...

Summary of the biochemistry notes best solutions Basic principles govern energy maniulations in cells - 1) Molecules are degrades or synthesized stepwise in a sries of reactions termed metabolic pathway. 2) ATP is the energy currency of life 3) ATP can be formed by the oxidation of carbon fuels 4) Metabolic pathways are highly regulate Oxidation - loss of electrons, Reducing agent(reductant)-donanates ectrons, oxidized. For every biological oxidation there is a corresponding reductio...
