What is a macromolecule?

Back

A macromolecule is a large complex molecule, such as proteins, nucleic acids (DNA and RNA), and carbohydrates, that are essential for life.

Front

Which macromolecule is primarily responsible for storing energy in living organisms?

Back

Carbohydrates, specifically in the form of starch.

Front

What are monosaccharides?

Back

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules like glucose and fructose.

Front

What is the role of ATP in cellular processes?

Back

ATP (adenosine triphosphate) provides energy for various cellular processes, including the movement of ions across cell membranes.

Front

Define polysaccharide.

Back

Polysaccharides are long chains of monosaccharide units linked together, serving as energy storage (like starch) or structural components (like cellulose).

Front

What is the difference between a disaccharide and a polysaccharide?

Back

A disaccharide consists of two monosaccharide units, while a polysaccharide consists of many monosaccharide units.

Front

What is the significance of sodium and potassium in the human body?

Back

Sodium and potassium are essential electrolytes that help maintain fluid balance, nerve function, and muscle contractions.

Front

Explain the term 'concentration gradient.'

Back

A concentration gradient refers to the difference in the concentration of a substance across a space, which drives the movement of substances from areas of high concentration to low concentration.

Front

What is the function of starch in plants?

Back

Starch serves as a storage form of energy in plants, allowing them to store glucose for later use.

Front

What is the primary function of proteins in the body?

Back

Proteins serve various functions, including building and repairing tissues, acting as enzymes, and supporting immune function.
