Active Transport

These flashcards cover the key terms and concepts related to Active Transport, including definitions of processes and components involved.

Active Transport

The process of moving molecules across a membrane against their concentration gradient using energy.

Carrier-mediated transport

Transport that involves carrier proteins to move substances across the cell membrane.

Endocytosis

The process of transporting large materials into the cell.

Exocytosis

The process of transporting materials out of the cell using Golgi bodies and transport vesicles. ex: waste, hormones(insulin), and neurotransmitters

Na/K pump

Carrier mediated active transport located in neurons that moves 3 sodium ions out of the cell and 2 potassium ions into the cell.

Electrogenic/H+/Proton pump

Active Transport Pump located in chloroplasts and mitochondria used to form ATP

Phagocytosis

A type of endocytosis known as 'cell eating', where solid materials are engulfed by the cell. ex: ameoba eating algae cells

Pinocytosis

A type of endocytosis known as 'cell drinking', where liquids are brought into the cell.

Receptor-mediated endocytosis

A process where receptor proteins facilitate the uptake of specific molecules, such as LDL cholesterol.

Contransport Pump

Active transport pump that is a combination of H+ pump and carrier proteins that bring in large molecules
