B3

Question 1

Organs

Answer 1

Something in the human body

Question 2

Tissue

Answer 2

any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.

Question 3

Digestive system

Answer 3

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. In this system, the process of digestion has many stages, the first of which starts in the mouth

Question 4

What is an enzyme

Answer 4

a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.

Question 5

Carbohydrate

Answer 5

A carbohydrate is a biological molecule consisting of carbon, hydrogen and oxygen atoms, usually with a hydrogen–oxygen atom

Question 6

Simple sugars

Answer 6

Monosaccharides, also called simple sugars, are the most basic units of carbohydrates. They are fundamental units of carbohydrates and cannot be further hydrolyzed to simpler compounds.

Question 7

Lipid

Answer 7

any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents.

Question 8

Fatty acids

Answer 8

a carboxylic acid consisting of a hydrocarbon chain and a terminal carboxyl group, especially any of those occurring as esters in fats and oils

Question 9

Protein

Answer 9

Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.

Question 10

Animo acid

Answer 10

a simple organic compound containing both a carboxyl (—COOH) and an amino (—NH2) group.

Question 11

Denature

Answer 11

destroy the characteristic properties of (a protein or other biological macromolecule) by heat, acidity, or other effect which disrupts its molecular conformation.

Question 12

Catalyst

Answer 12

a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

Question 13

Active site

Answer 13

a region on an enzyme that binds to a protein or other substance during a reaction.

Question 14

Metabolism

Answer 14

Metabolism is the set of life-sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes

Question 15

Amylase

Answer 15

An amylase is an enzyme that catalyses the hydrolysis of starch into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion.

Question 16

Protease

Answer 16

A protease is any enzyme that performs proteolysis; protein catabolism by hydrolysis of peptide bonds.

Question 17

Lipase

Answer 17

A lipase is any enzyme that catalyzes the hydrolysis of fats. Lipases are a subclass of the esterases. Lipases perform essential roles in the digestion, transport and processing of dietary lipids in most, if not all, living organisms

Question 18

A bile

Answer 18

a bitter greenish-brown alkaline fluid which aids digestion and is secreted by the liver and stored in the gall bladder.
