Molecules are defined as the smallest particles of a chemical compound or an element, and are made up of atoms. Cells are made up of semi permiable membranes that only allow selected materials to move in or out of the cell, therefore due to the big size of molecules compared to atoms the membrane doesn't allow their passage in the cell. Therefore the cell doesn't allow most molecules to diffuse passively to the cell. Secondly, molecules that can enter the cell requires specific carriers carriers that will enable entry of small molecules in the cell.
It becomes positive because ATP synthase allows H+ ions to pass through the membrane .
Answer:
The correct answer is - they both have highly folded membranes.
Explanation:
Organelles such as the endoplasmic reticulum, Golgi apparatus, and mitochondria have highly folded double membranes. This highly folded membrane provides the increased surface area in the organelle.
As the inner membrane of these organelles is the site for many chemical reactions the highly folded or layered membranes get more space for such reactions to occur due to increased surface area.
Answer:
The environment will impact positively if the human activities are positive and negative if the human activities are negative. It is worthy of note that our actions and activities contribute greatly to the way and manner our environment response to us.
