WebPlant and bacterial cells usually use hydrogen ions as the driving substrate; sugars and amino acids are the most common driven substrates. When the bacterium Escherichia coli must metabolize lactose, it co-transports hydrogen ions with lactose (which can reach a concentration 1,000 times higher than that outside the cell). Primary active transport WebActive transport: moving against a gradient. To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of …

Web17 de dez. de 2024 · 5.4: Active Transport. Distinguish between primary active transport and secondary active transport. Active transport mechanisms require the use of the … WebHowever, with secondary active transport, ATP is not directly involved in the pumping of the solute. Instead, this process uses the energy stored in concentration gradients to move the solute. Since sodium is always in a higher concentration outside of the cell (due to primary active transport), the sodium gradient is often used to power ... greatway financial mississauga
