because those that can't get through the membrane by themselves can get help. transport proteins give them a ride through the membrane. different transport proteins make it easier for certain molecules to get through the membrane without cell using energy
Things like oxygen, CO2 and lipids cross the membrane with simple diffusion. Water can cross the membrane with osmosis when the water moves through a channel protein in the plasma membrane. Glucose, potassium, sodium etc. moves through a carrier protein in the membrane with the process of active movement. In the process of active movement energy is needed and it is given by the glucose or ATP from the cell.
fat is broken down into fatty acids
When large materials are being transported through the membrane
It is a type of active transportation.So energy is needed.

When food is broken down the stored energy is in your cells. When the energy is needed, the cells release the energy.
It is energy for our body's cells, that is broken down by the cells when energy is needed.

they are broken down into water and carbon dioxide and in this process energy is released
It is stored in bonds and released in energy. Energy is needed to break the chemical bonds, and energy is released when bonds are broken.
It passses them down a chain of proteins. These proteins use the energy in the electrons to create concentration gradients, which build up on one side of the membrane. Im pretty such off the top of my head that this concentration is of H+ atoms inside the inner membrane of the mitochondria, but im not positive. Anyways, once this concentration is great enough, the particles go through what is known as chemiosmosis, in which they go through a protein in the membrane called ATP synthase, which acts a kind of pump. this pump is powered by this concentration gradient, and as H+ ions go out of the membrane through this pump, they give the energy needed to phosphorylate ADP into ATP, making energy.
Glycogen is the long-term energy storage for animals and most of an animals energy is exerted through motility or muscle movement so it would only make sense for glycogen to be broken down (through hydrolosis) where it was most needed; in the muscles.
