Introduction to Chemistry Quiz

Definition of Chemistry

• Chemistry is the branch of science that studies the composition, structure, properties, and changes of matter.
• It involves understanding the interactions and transformations that occur among various substances.

Chemical Reaction

• A chemical reaction is a process in which substances (reactants) undergo a transformation to form new substances (products).
• This process involves the breaking of chemical bonds and the formation of new ones, often accompanied by energy changes.

Metabolism Categories

• Catabolism is the category of metabolism that involves breaking down molecules to obtain energy.
• It includes processes like glycolysis and the Krebs cycle, which convert complex molecules into simpler ones, releasing energy.

Purpose of Metabolism

• The main purpose of metabolism is to convert food into energy and building blocks for growth, repair, and maintenance of cells.
• It encompasses both catabolic and anabolic processes, ensuring the body functions properly and efficiently.

Mixtures in Chemistry

• A mixture is a combination of two or more substances that retain their individual properties and can be separated by physical means.
• Mixtures can be homogeneous (uniform composition) or heterogeneous (distinct, separate components).
