WebInstead, the cell must bring in more glucose molecules via active transport. In active transport, unlike passive transport, the cell expends energy (for example, in the form of ATP) to move a substance against its concentration gradient.

Active Transport - The Definitive Guide | Biology Dictionary
WebMay 16, 2020 · Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active …
WebActive transport requires assistance from carrier proteins, which change conformation when ATP hydrolysis occurs. Common mistakes and misconceptions. Active transport is not the same as facilitated diffusion. Both active transport and facilitated diffusion do use proteins to assist in transport.
Web5.3: Active Transport. Page ID. OpenStax. Skills to Develop. Understand how electrochemical gradients affect ions. Distinguish between primary active transport and secondary active transport. Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).
WebActive 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.
Web2.2.4: Active Transport. Page ID. OpenStax. Learning Objectives. By the end of this section, you will be able to do the following: Understand how electrochemical gradients affect ions. Distinguish between primary active transport and secondary active transport.
Web(A red blood cell uses most of its metabolic energy to maintain the imbalance between exterior and interior sodium and potassium levels that the cell requires.) Because active transport mechanisms depend on a cell’s metabolism for energy, they are sensitive to many metabolic poisons that interfere with the ATP supply.
