[3] Learning Catalytics Flashcards
When observing the synthesis of a biological macromolecule, more of what should appear?
water
Molecules that are soluble in water have which type of bond?
polar covalent bond
Which falls under one of the categories of macromolecules? cholesterol lipid nucleic acid protein carbohydrate
cholesterol
Which provides the most compact energy storage?
lipids
nucleic acids
carbohydrates
proteins
All provide about the same amount of energy stored per unit volume.
lipids
For what is water most important when digesting food?
hydrolysis reaction
What is true for double bonds?
Unsaturated fats have double bonds and are associated with good cardiovascular health.
Double bonds are weaker than single bonds.
Cis double bonds are made artificially in food processing and are associated with poor cardiovascular health.
Trans double bonds are found in nature and are associated with cardiovascular health.
Double bonds keep molecules straight.
Unsaturated fats have double bonds and are associated with good cardiovascular health.
Which polysaccharide has the greatest number of branches?
glycogen
From what are polysaccharides made?
monosaccharides
If you were given a sample of a polysaccharide and told that the only subunit was glucose, what would you have?
You cannot know from the information given.
All lipids are made from glycerol and fatty acids. are poorly water soluble. have low energy content. contain nitrogen. are acidic when mixed with water.
are poorly water soluble
Which falls outside the lipids? estrogen glucose triacylgyceride trans fat cholesterol
glucose
If you were asked to chose a lipid subunit, which would you choose?
Fatty Acid
Which is least important for metabolism? structural protein hormonal protein enzymatic protein contractile protein receptor protein
structural protein
