Chapter 1: Help Chemical Reactions

Vocabulary flashcards covering chemical reaction types, metabolism, energy, nutrients, and solutions based on the lecture transcript.

Exchange reactions

Reactions where parts of different molecules trade places.

Reversible reactions

Reactions where products can become reactants, or reactants can become products.

Equilibrium

The balance of synthesis and decomposition reactants.

Metabolism

All of the chemical reactions in the body.

Enzymes

Proteins that help chemical reactions happen.

Activation energy

The amount of energy necessary for a reaction to begin.

Catalysts

Atoms or molecules that change the rate of a chemical reaction without being consumed or changed in the process.

Exergonic reactions

Reactions that release energy.

Endergonic reactions

Reactions that absorb energy.

Inorganic substances

Substances that are without carbon.

Inorganic sub nutrients

Essential elements and molecules gotten from the diet.

Metabolities

Substances made up or broken down by our bodies.

Organics

Substances that contain carbon.

Solutions

A mix of a solvent and a solute.

Ionization

Ionic bonds breaking and ions attached to polar water molecules.

PH

The measurement of the concentration of hydrogen ions in a solution.
