There are four classes of organic nutrients. Which of following correctly characterizes the given energy nutrient? Carbohydrates—provide the body with an immediate source of energy Carbohydrates—composed of amino acids bound together with peptide bonds Proteins—have three forms: monosaccharides, disaccharides, and polysaccharides Proteins—make up the bulk of the plasma membrane of cells Lipids—structural components of hair, fingernails, and claws

Carbohydrates—provide the body with an immediate source of energy

When a car burns gasoline, much of the energy is released in the form of heat. Which of the following best describes this process in relation to the first law of thermodynamics?

Energy is conserved. Energy can be changed from one form to another.Correct All energy comes from the sun. Energy is often destroyed. Energy is always used up in reactions.

Digestion of energy nutrients requires specific enzymes for each molecule. Which of the following enzymes is incorrectly matched with its corresponding molecule? Lactose-lactase Fats-lipase Starch-amylase Sucrose-maltase

Sucrose-maltase

The second law of thermodynamics states that

chemical energy is readily converted into solar energy. during the transfer of energy, some energy is lost as heat.Correct ATP is the only form of energy used by the cell. energy is always conserved. cellular activities require little ATP to function.

If there were no solar energy, humans would not be affected because they rely on chemical energy. Group starts

false

Polymers are formed by hydrolytic reactions of monomers. t or f

false

fat-soluble nutrientsCorrect

The ______ law of thermodynamics explains the transfer of solar energy into chemical energy.

first

Like all nutrient class, carbohydrates are broken down at multiple points throughout digestion. In the small intestines, monosaccharides and disaccharides are absorbed.Correct fiber is used by some bacteria. fiber bulks to form feces. starch breakdown ends with the increase of pH causing amylase denaturing.
