Question 1

Chemical reactions that build body tissue are considered&#10;A) anabolic&#10;B) catabolic&#10;C) thermodynamic&#10;D) exergonic

Accepted Answer

Anabolic reactions are those that build complex molecules from simpler ones, which is essential for the formation and repair of body tissues.

Question 2

Saliva, secreted by special glands in the mouth, contains&#10;A) amylase&#10;B) bile&#10;C) hydrochloric acid&#10;D) trypsin

Accepted Answer

Saliva contains amylase, an enzyme that begins the breakdown of starches into sugars in the mouth.

Question 3

Little or no absorption takes place in the stomach except for&#10;A) fatty acids&#10;B) amino acids&#10;C) sugars&#10;D) alcohol

Accepted Answer

Alcohol is one of the few substances that can be absorbed directly through the stomach lining into the bloodstream.

Question 4

Where is bile produced?&#10;A) Pancreas&#10;B) Stomach&#10;C) Small intestine&#10;D) Liver

Accepted Answer

Bile is produced by the liver. It helps in the digestion and absorption of fats in the small intestine.

Question 5

The enzyme amylase digests&#10;A) protein&#10;B) lipid&#10;C) carbohydrate

Accepted Answer

Amylase is an enzyme that catalyzes the breakdown of carbohydrates, specifically starches, into simpler sugars like maltose and glucose.

Question 6

Movement of molecules down their concentration gradient (i.e., from a region of high concentration to a region of low concentration) using protein carriers is called&#10;A) osmosis&#10;B) passive diffusion&#10;C) facilitated diffusion&#10;D) active transport

Accepted Answer

Facilitated diffusion is the process where molecules move down their concentration gradient (from high to low concentration) across a cell membrane with the help of carrier proteins, without the expenditure of energy.
