What enzyme found in the stomach breaks chemical bonds between the amino acid monomers and proteins?

• amylase

• chyme

• pepsin

• lipase

This organ produces juices that have enzymes that digest carbohydrates, proteins, and lipids, as well as bases to neutralize the stomach acid.

• pancreas

• small intestine

• gallbladder

• liver

Short-chain triglycerides found in foods such as butterfat molecules in milk are split by a specific enzyme in preparation for absorption. Which of the following enzymes are responsible?

• amylase

• lipase

• trypsin

• pepsin

What is the most important factor that creates specificity of enzymes?

• temperature

• pH

• shape

• carbohydrates

Vitamins are critical to a well-balanced diet because they are used to make

• bile

• coenzymes

• chyme

• ATP

Enzymes work by

• making chemical reactions proceed spontaneously

• working on any substrate

• being used up in the chemical reaction

• lowering the activation energy of a reaction

If two phosphate groups are removed from the energy molecule of cells, what would result?

• ATP

• ADP

• AMP

• Glucose

Glucose is obtained from the foods that you eat. Why does your body need glucose?

• It keeps you from getting too hungry.

• It is a product of cellular respiration which makes about 36 ATP

• It is necessary to breakdown ATP to release energy

• It is a reactant of cellular respiration which makes about 36 ATP.
