## Step 1The question is asking about the process by which cells transport large molecules, such as glucose, across the plasma membrane from areas of high to low concentration. The options provided are ATP, osmosis, active transport, and facilitated diffusion.## Step 2ATP (Adenosine Triphosphate) is a molecule that provides energy for many cellular processes, but it is not a process itself. Therefore, it is not the correct answer.## Step 3Osmosis is a process that involves the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. This process does not involve the transport of large molecules like glucose, so it is not the correct answer.## Step 4Active transport is a process that uses energy to move molecules against their concentration gradient, from areas of low concentration to areas of high concentration. This process is not used for the transport of large molecules like glucose, so it is not the correct answer.## Step 5Facilitated diffusion is a process that uses transport proteins to move molecules across the plasma membrane from areas of high concentration to areas of low concentration. This process does not require energy and is used for the transport of large molecules like glucose. Therefore, it is the correct answer.
