What type of molecules pass directly through the membrane? (Passive transport)

What would happen to the flow of molecules across a membrane if ATP was broken down? (Active transport)

Answer :

hwilson72

Answer:

The plasma membrane is selectively permeable; hydrophobic molecules and small polar molecules can diffuse through the lipid layer, but ions and large polar molecules cannot.

ATP is an energy molecule, and when hydrolysis happens, it gets broken down to release the energy that was stored in its chemical bonds.

Molecules that can pass directly through the membrane are - small and simple types of molecules through passive transport.

During Active transport, if ATP was broken down then the flow of molecules will not be able to move molecules across the membrane.

Passive transport is a type of transport of molecules that does not require energy to transport or move molecules across the membrane.

  • Such transport allows the molecule to move across the cell membrane, to the concentration gradient.
  • Diffusion is the type of passive transport.
  • this transport takes place for the molecules that are very small and simple molecules such as water, oxygen, carbon dioxide, and others.

Active transport is a type of transport that requires energy or ATP to transport molecules across the membrane.

  • takes place against the concentration gradient
  • require channel or pump
  • Transport the large molecules such as ions, glucose, protein, and others.
  • If the ATP is not enough or breakdowns then there would be no active transport as it requires ATP molecule or energy.

Thus, the correct answer is - Molecules that can pass directly through the membrane are - small and simple types of molecules through passive transport.

During Active transport, if ATP was broken down then the flow of molecules will not be able to move molecules across the membrane.
