Why does the active transport require energy?
Active transport requires energy to move substances across a plasma membrane, often because the substances are moving from an area of lower concentration to an area of higher concentration or because of their large size.
Why does active transport require ATP energy quizlet?
Active transport requires energy as it is working against a concentration gradient and needs energy to rotate the protein transporting the solute. The energy is produced in respiration and comes from the mitochondria.
What transport requires ATP?
Does secondary active transport require ATP?
Secondary active transport (cotransport), on the other hand, uses an electrochemical gradient – generated by active transport – as an energy source to move molecules against their gradient, and thus does not directly require a chemical source of energy such as ATP.
Does all active transport require ATP?
Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Which of the following is an example of secondary active transport?
An example of secondary active transport is the movement of glucose in the proximal convoluted tubule.
What type of transport is Symport?
Symporters and antiporters are involved in active transport. Antiporters transport molecules in opposite directions, while symporters transport molecules in the same direction.
What is tertiary active transport?
TERTIARY ACTIVE TRANSPORT This is type of active transport in which the energy is derived from energy that has been stored in the form of ionic concentration differences from secondary active transport of substances between the two sides of a cell membrane, created originally by primary active transport.
