- 2. Circle the correct bolded blue word. a. A substance that moves across a membrane "down" or "with" their concentration gradient is moving from the side with a higher / lower concentration of that substance to the side with a higher / lower concentration. This does / doesn't require energy input and is called active / passive transport. b. A substance moving "against" or "up" its concentration gradient is moving from the side with a higher / lower concentration of that substance to the side with a higher / lower concentration. This does / doesn't require energy input and is called active / passive transport. c. If the energy from the hydrolysis of ATP is directly used to pump the substance, the transport is called primary /secondary active transport. d. Ion-coupled transport is primary /secondary active transport and has two parts. First, the hydrolysis of ATP is used to power the creation of an ion concentration gradient. The ion is typically Na* or H*.
