Which one of the following is active transport?

Explanation: Active transport is the movement of molecules across a cell membrane from a lower concentration to a region of higher concentration - against the concentration gradient. It requires cellular energy to achieve this movement.

What are active transport 5 examples?

Here are some examples of active transport in animals and humans:

Sodium-potassium pump (exchange of sodium and potassium ions across cell walls)
Amino acids moving along the human intestinal tract.
Calcium ions moving from cardiac muscle cells.
Glucose moving in or out of a cell.
A macrophage ingesting a bacterial cell.

What are the three types of active transport?

Types of primary active transporters

P-type ATPase: sodium potassium pump, calcium pump, proton pump.
F-ATPase: mitochondrial ATP synthase, chloroplast ATP synthase.
V-ATPase: vacuolar ATPase.
ABC (ATP binding cassette) transporter: MDR, CFTR, etc.

Is an example of active transport?

Examples of Active Transport Phagocytosis of bacteria by Macrophages. Movement of Ca2+ ions out of cardiac muscle cells. Transportation of amino acids across the intestinal lining in the human gut. Secretion of proteins like enzymes, peptide hormones, and antibodies from different cells.

What are 2 active transport?

Active transport is primarily of two types, primary and secondary active transport. The primary active transport is uniport, whereas, in the secondary active transport, the uphill transfer of molecules across the membrane is coupled through the transfer of an ion or other molecule down the gradient.

What are types of active transport?

There are two main types of active transport: Primary (direct) active transport – Involves the direct use of metabolic energy (e.g. ATP hydrolysis) to mediate transport. Secondary (indirect) active transport – Involves coupling the molecule with another moving along an electrochemical gradient.

What is active transport process?

Active transport is the energy-requiring process of pumping molecules and ions across membranes "uphill" - against a concentration gradient. The active transport of small molecules or ions across a cell membrane is generally carried out by transport proteins that are found in the membrane.

What are 3 examples of passive transport?

Types Of Passive Transport

Simple Diffusion.
Facilitated Diffusion.
Filtration.
Osmosis.

What is an example of a transport?

Examples of road transport: Buses, rickshaws, trucks, scooters, motorcycles, and cars.

What is an example of active transport quizlet?

exocytosis is an example of active transport and requires the use of cellular energy. A gland cell releases hormones through the process of exocytosis.

Which is not an example of active transport?

Osmosis, diffusion and facilitated diffusion are some of the examples of passive transport. Thus, facilitated diffusion is not an example of active transport because it does not require energy for transport of molecules.

What is simple active transport?

Active transport is the process of moving molecules across a cellular membrane through the use of cellular energy. Credit: Anna Kireieva/Shutterstock.com. The alternative to active transport is passive transport, which uses kinetic energy only to move the molecules.

Is osmosis active transport?

Osmosis is a form of passive transport when water molecules move from low solute concentration(high water concentration) to high solute or low water concentration across a membrane that is not permeable to the solute. There is a form of passive transport called facilitated diffusion.

What is active transport chain?

Active transport is a type of cellular transport in which substances (e.g. ions, glucose, and amino acids) are transported across a biological membrane towards the region that already contains a lot of such substances.

Is diffusion A active transport?

Diffusion is a passive process, but active transport requires metabolic energy or an electrochemical gradient for the transportation of molecules across the membrane. Simple diffusion occurs directly through the cell membrane.

What are examples of primary active transport?

Primary Active Transport: Sodium-potassium pump, calcium pump in the muscles, and proton pump in the stomach are the examples of the primary active transport.

What are examples of active process?

Exocytosis, endocytosis and sodium-potassium pump are a few examples of active transport. The process of endocytosis and exocytosis are utilized by all the cells for transportation of molecules which cannot passively permeate via the membrane.

What is an example of active transport in plants?

Plants use active transport in the following ways: Calcium moves between cells with the use of ATP energy. Minerals pass via a stem on their way to different areas of the plants. Root pressure transports water from the plant roots to other plant cells.

What are the 4 main types of passive transport?

The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.
