Describe active transport biology
WebActive transport describes the use of energy to move molecules across a cell membrane, usually against their concentration gradients. Membrane proteins involved in active transport include symporters, antiporters, and the sodium-potassium pump. Sort by: Top Voted Questions Tips & Thanks Want to join the conversation? Dovid Shaw 7 years ago WebApr 9, 2024 · Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient—that is, if the concentration of the substance inside the cell is greater than its concentration in the extracellular fluid (and vice versa)—the cell must use energy …

WebApr 8, 2024 · Views today: 3.76k. The movement of a substance across the cell membrane is known as cell transport. The substance can move either in or out of the cells. There are various molecules that pass through the plasma membrane or the cell membrane. The plasma membrane is highly selective in nature. WebActive transport process is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a lower to higher concentration. Thus, this is an important process …
WebActive transport is the movement of substances from an area of low concentration to a higher concentration , either into or out of cells. During active transport, carriers in the cell membrane ‘pick up’ particles and move them against the concentration gradient. As the name suggests, active transport requires energy from the cell, which is ...

WebDec 1, 2024 · Figure 17.2. 2: Sieve-tube elements are the conducting cells of the phloem in angiosperms. Assimilate travels through perforations in sieve plates (labeled sieve-tube plates), which connect stacked sieve-tube elements. Neighboring companion cells carry out metabolic functions for the sieve-tube elements and provide them with energy.
