What is a monosaccharide?

Back

A monosaccharide is a simple sugar that is the most basic form of carbohydrates, consisting of a single sugar molecule. Examples include glucose and fructose.

Front

What is an enzyme?

Back

An enzyme is a protein that acts as a catalyst in biological reactions, speeding up the rate of specific reactions without being consumed in the process.

Front

What is a polysaccharide?

Back

A polysaccharide is a carbohydrate that consists of long chains of monosaccharide units bonded together. Examples include starch, glycogen, and cellulose.

Front

What are carbohydrates?

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, and they serve as a major source of energy for the body.

Front

What is an active site?

Back

The active site is the specific region on an enzyme where the substrate binds, allowing the enzyme to catalyze a reaction.

Front

What are lipids?

Back

Lipids are a group of organic compounds that are insoluble in water, including fats, oils, and waxes, and they serve as energy storage and structural components of cell membranes.

Front

What is the role of substrates in enzymatic reactions?

Back

Substrates are the reactants that enzymes act upon, binding to the active site of the enzyme to form products.

Front

What is the difference between saturated and unsaturated fats?

Back

Saturated fats contain no double bonds between carbon atoms, while unsaturated fats contain one or more double bonds, affecting their physical state at room temperature.

Front

What are nucleic acids?

Back

Nucleic acids are macromolecules, such as DNA and RNA, that store and transmit genetic information.

Front

What is the function of proteins in the body?

Back

Proteins serve various functions in the body, including structural support, transport, enzymes, and immune response.
