What requires energy from ATP hydrolysis?The energy derived from exergonic ATP hydrolysis is used to pump sodium and potassium ions across the cell membrane. The hydrolysis of one ATP molecule releases 7.3 kcal/mol of energy (∆G = −7.3 kcal/mol of energy).
Does active transport require ATP hydrolysis?The movement of one ion does not provide the chemical potential thermodynamic driving force to move the other. Rather the hydrolysis of ATP is required. So this protein can be called a uniport active transporter for two different ions.
Which of the following requires energy from ATP quizlet?Which of the following processes requires ATP? Exocytosis is a form of vesicular transport. All vesicular transport processes are active processes that require ATP.
