Front

What are monosaccharides?

Back

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

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy, relying on concentration gradients.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that uses protein channels to help move molecules across the cell membrane.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that involves the breaking down of substances into simpler molecules or the building up of complex molecules.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base, and they play a key role in storing genetic information.

Front

What is the function of carbohydrates in plants?

Back

Carbohydrates, such as starch, serve as energy storage in plants, providing energy when needed.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.

Front

What is chemical equilibrium?

Back

Chemical equilibrium is the state in which the concentrations of reactants and products remain constant over time in a reversible chemical reaction.

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required.
