26.1.4 Lipids Flashcards
Which statement about lipids is not correct?
Lipids provide less energy than glucose.
The lipid shown in the drawing is used to make cell membranes.
Which statement about lipids, lipid bilayers, or cell membranes is not correct?
A lipid bilayer has lipids whose polar heads point to the center of the bilayer, while the hydrocarbon tails point toward the outside of the bilayer.
Which statement about glucose and triglycerides is not correct?
Triglycerides are already mostly oxidized.
Which statement about saturated or unsaturated triglycerides is not correct?
Unsaturated fats in your diet can lead to solid masses in arteries.
Which statement about cholesterol is not correct?
Cholesterol is transported to other parts of the body by lipoproteins. Cholesterol is flushed from the body through proteins other than lipoproteins.
Lipids are _________________
biological molecules that are soluble in organic solvents but insoluble or sparingly soluble in water.
Which statement about lipids is not correct?
Lipids are biochemical substances that can easily move on their own throughout the body.
Which statement about cell membranes is not correct?
The lipids that make up cell membranes have short hydrocarbon tails that are soluble in water.
Glucose and triglycerides are storage molecules for energy in the body. Which statement best describes how glucose and triglycerides provide energy?
Glucose and triglycerides are oxidized. As a result, they are converted to a fuel called ATP.
The principal difference between saturated and unsaturated triglycerides is ______________
the presence (or absence) of one or more alkene group.
