Exam: GRE (Verbal)

Definition: A chemical process where a compound forms a complex with a metal ion, often used to remove harmful metals from the body or solutions.

Example: Chelation therapy is often used to treat heavy metal poisoning.

Definition: A substance that can bind to metal ions and remove them from solutions or biological systems.

Example: The doctor prescribed a chelator to help remove excess metals from the patient's body.

Definition: Relating to the science of chemistry or the substances involved in it.

Example: The chemical reaction produced a lot of heat and light.

Definition: A substance that has a specific molecular structure and is created or used in a process involving chemical reactions.

Example: The laboratory tested various chemicals to find a cure for the disease.

Definition: In a way that relates to chemistry or involves chemical processes.

Example: The substances were chemically altered to improve their effectiveness.

Definition: Related to a process in cells where energy is produced by the movement of ions across a membrane, helping to create ATP, which is a key energy source for many biological functions.

Example: The chemiosmotic process is essential for energy production in both plants and animals.

Definition: The force that causes atoms to join together to create chemical compounds, often referred to as chemical attraction or affinity.

Example: The chemism between the atoms allowed them to form a stable compound.

Definition: To take up and chemically bind a substance onto the surface of another substance.

Example: The catalyst can chemisorb reactants to enhance the reaction rate.

Definition: The process where a substance sticks to the surface of another substance through chemical bonds instead of just physical attraction.

Example: Chemisorption is important in catalysis because it allows reactants to bond strongly to the catalyst's surface.

Definition: A person who studies or works in the field of chemistry, often involved in experiments and research related to substances and their properties.

Example: The chemist conducted experiments to develop a new type of medicine.

Definition: A process by which certain organisms obtain energy through chemical reactions instead of using sunlight.

Example: Some bacteria survive in extreme environments by using chemoautotrophy to produce energy.
