Which of the following statements are true about lipids?  There may be more than one correct answer so make sure to check all answers that are true.   Fats tend to be liquid at room temperature while oils tend to be solid.   A saturated fat contains fatty acids that only have single bonds between each carbon in the carbon chain.   The presence of multiple double bonds in a fatty

What characteristic is common to all lipid molecules? The are composed of primarily carbon and oxygen atoms. They are most typically charged molecules. They are only located in cell membranes. They do not dissolve in water.

Monosaccharides should always have at least two hydroxyl group. True or False? Monosaccharides can have two or more aldehyde groups in one structure. True or False? Both aldehyde group and ketone group are always present in a monosaccharide. True or False? All carbons of monosaccharide should have at least one hydroxyl group. True or False?

Glycerin, bound to three fatty acids, forms a ____ fat, which is also called neutral fat.   cholesterol  steroid  triglyceride phospholipid

What is the molecular structure responsible for creating differences between saturated and unsaturated fats? Double and Triple Bonds Polar Covalent Bonds O Hydrophobicity O Nonpolar Covalent Bonds

Which of the following regarding disulfide bonds is/are true? Disulfide bonds are the most common intrachain covalent linkage in proteins Disulfide bond formation is critical for correct protein folding into the native conformation Disulfide bonds impart a large degree of stability to the secondary structure of proteins The intracellular environment is too oxidizing to allow disulfide bond formation A and D

None

The figure below illustrates partial models of a starch molecule and a cellulose molecule, two carbohydrate polymers that are each made of covalently bonded glucose molecules. Starch A B CH₂OH C OH D OH CH₂OH OH OH 0 CH₂OH OH Partial models of a starch and a cellulose molecule Cellulose OH OH OH CH₂OH 0 CH₂OH OH Which of the following best explains why human enzymes that can digest starch cannot also digest cellulose despite the fact that they are both polymers of glucose? OH CH₂OH OH OH Human enzymes can only facilitate the digestion of starch because starch is formed via a dehydration synthesis reaction. The breakdown of starch involves a catabolic reaction, but the breakdown of cellulose Involves an anabolic reaction, which does require enzymatic catalysis. The polymers are digested differently because starch is primarily used for energy stor age while cellulose is primarily used as the component of plant cell walls. The biomolecular differences between the polymers prevent…
