30s - Q2
Which of the following is not a lipid?
lipase
fat
phospholipid
steroid
30s - Q3
Which of the following describes the difference between a phospholipid and a fat?
Phospholipids have one more fatty acid than fats.
Phospholipids are nonpolar and fats are polar.
Phospholipids are polar and fats are nonpolar.
Phospholipids have one less fatty acid than fats.
30s - Q4
Phospholipids are amphipathic. Which of the following describes how that term applies to phospholipids?
The phosphate group is nonpolar and the fatty acids are polar.
The phosphate group is polar and the fatty acids are nonpolar.
The phosphate group can amplify signal transduction by phosporylating signaling molecules.
The fatty acids can amplify signal transduction by phosporylating signaling molecules.
30s - Q5
Steroids are a type of hormone. Polar materials require a transport protein while nonpolar materials can pass easily through the plasma membrane. Which of the following describes how steroid hormones enter the cell?
Steroids are polar so they pass easily through the plasma membrane.
Steroids are nonpolar so they pass easily through the plasma membrane.
Steroids are nonpolar so they require a transport protein to pass through the plasma membrane.
Steroids are polar so they require a transport protein to pass through the plasma membrane.
30s - Q6
Which of the following describes the differences between saturated and unsaturated fatty acids?
Saturated fatty acids are more polar than unsaturated fatty acids.
Unsaturated fatty acids are more polar than saturated fatty acids.
Saturated fatty acids have more double bonds than saturated fatty acids.
Unsaturated fatty acids have more double bonds than saturated fatty acids.
30s - Q7
Lipids are polymers.
falsetrueTrue or False30s - Q8
Which of the following describes the function of cholesterol (a steroid) in the plasma membrane?
Cholesterol provides energy for active transport across the membrane.
Cholesterol acts as a receptor molecule to bind to signaling molecules in the signal transduction pathway.
Cholesterol binds to the fatty acid tails to maintain fluidity of the membrane.
Cholesterol is a polar compound that aids in the transport of polar substances across the membrane.
30s - Q9
Which of the following describes the process to add a fatty acid to the glycerol in a triglyceride?
This is a dehydration reaction leading to water used.
This is a hydrolysis reaction leading to water used.
This is a hydrolysis reaction leading to water loss.
This is a dehydration reaction leading to water loss.
30s - Q10
Which of the following describes why lipids are hydrophobic?
Lipids are gaseous materials that do not dissolve in water.
Lipids have hydrogen bonds that repel the hydrogen bonds in water.
Lipids have more neutrons on their atoms making the compound neutral.
Lipids are composed mostly of hydrocarbons which is nonpolar.
