What is a sentence for active transport?

What is a sentence for active transport?

The proximal tubule is the site of most secretion, reabsorption, and active transport. Uric acid, formed from nucleic acids, is reabsorbed from filtrate by active transport, and a small portion is actively secreted into the urine.

What is active transport give examples?

Active transport is usually associated with accumulating high concentrations of molecules that the cell needs, such as ions, glucose and amino acids. Examples of active transport include the uptake of glucose in the intestines in humans and the uptake of mineral ions into root hair cells of plants.

What is active transport in simple words?

Definition of active transport : the movement of a chemical substance by the expenditure of energy against a gradient in concentration or in electrical potential across a plasma membrane — compare passive transport.

What is a sentence for passive transport?

Osmosis and diffusion is called passive transport because it takes no energy to move from a high concentration to a low concentration. This clearance was mediated by both active and passive transport processes.

What is another word for active transport?

Thus, secondary active transport is also called coupled transport or cotransport. Coupled transport is defined as the simultaneous transport of two substances across a biological membrane.

Which one of the following is active transport?

Active Transport involves the transportation of a substance from a low concentration to a high concentration, against the diffusion gradient. The use of energy released through respiration helps in making the process sufficiently exergonic.

Is walking active transportation?

Promote Active Transportation. Active transportation is any self-propelled, human-powered mode of transportation, such as walking or bicycling. Many Americans view walking and bicycling within their communities as unsafe due to heavy traffic and a scarcity of sidewalks, crosswalks, and bicycle facilities.

How do you use active transport in a sentence?

Can you use active transport in a sentence. Active transport is the moving of molecules across the membrane of the cell against the concentration gradient with the use of ATP . Low to high concentration. Concentration gradient is the diffusion (movement of molecules from regions of low concentration) from high to low with the gradient.

Which statement about active transport is true?

Active transport is a mode of transportation in plants, which uses stored energy to move the particles against the concentration gradient. In a plant cell, it takes place in the root cells by absorbing water and minerals. Active transport always leads to accumulation of molecules are ions towards one side of the membrane.

What is the purpose of active transport?

Active transport is when molecules move across a cell membrane from a lower concentration to a higher concentration. This takes energy, often from adenosine triphosphate (ATP). Active transport is done so cells get what they need, such as ions, glucose and amino acids.

What is the definition of active transport?

Active transport. In contrast to passive transport, the active transport involves the movement of a substance (e.g. ions, glucose, and amino acids) across a membrane from a region of its lower concentration to a region of its higher concentration against a concentration gradient. Since it is against the concentration gradient,…
