Question

Question 23 (2.5 points) Saved Which of the following is true? Bile salts are amphipathic, which means they can act as an acid or a base. In the intestines, triacylglycerols must be broken down to monoacylglycerol and two fatty acids for transport into intestinal cells. Cholesterol is a hydrophilic molecule. Lipoprotein lipase is activated by B48 and B100. Question 24 (2.5 points) Saved Which of the following membrane lipids is a glycerophospholipid Osphingomyelin O Cerebroside O Phosphotidylinositol Gangliosides Question 25 (2.5 points) Saved Which of the following is a rotating part of the ATP synthase enzyme? The stator All these answers describe portions of the enzyme that are stationary. The alpha3-beta3 hexameric ring The C-ring

Hi the automatic grader for my biochemistry assignment is saying im getting things wrong but i cannot figure out which. Please tell me which are wrong with corrected answers. Thanks!

DUE AT MIDNIGHT PLEASE HELP ASAP

Answer 1

23 statement 2 is correct

.bile salts are amphiphatic that means they have hydrophobic end that is libid soluble and hudrophilic end which is water soluble . this means this statement is wrong they are not both acidic or basic

in the intestine the trylglycerol is broken doen into monoacylglycerol and free fatty acid . this process is called lyposis.therfore this statement is true

cholestrol molecule is amphiphatic means both hydrophilic and hydrophobic .therefore this is wrong statement .

apo c 11 is used to activate ..and above stement is wrong

24-phosphotidylinositol is classified as glycerophospholipid that contain a glycerol backbone two non polar fatty acid tails,a phosphate group,substituted with inositol polar head group so option 3 is correct .

25.option 4 is correct

rotatorty part of atp syntesase is proton or sodium gradient .the rotation of c ring produces the rotation of y subunit that leads atp synthesase .

non rotatory part is stator stalk .

29.false.

ketone bodies are formed in mitrocondrial matrix by lipolysis when glucose and sugar content is low.

30. option 4 is correct as RBC does not contain mitrocondria it does not synththise fatty acid .

31.vitamin a is not a derivative .

major derivatives of cholestrol are bilke salts steroid and harmones.

some of other derivatives are bile salt,vitamin d,etc

32option 3 is correct

as phosphate pentose cycle is general do not produce ADP .so we see it with calvin cycle and forms a three dimentional view in which it enhance both oxidative and non oxidative part
