limiting calorie intake and increasing energy needs
mitochondria
To get energy. Sugars are particularly important fuel molecules. They are oxidized in the food we eat and must be broken down into smaller molecules before our cells can use them.
well, enzymes are proteins that break up food molecules and digestion is when large protein molecules are broken down
The difference in solute concentration between cells and their environments, also known as osmotic gradient, causes water to move through cell membranes. Water molecules move from an area of lower solute concentration to an area of higher solute concentration in an attempt to equalize the concentration on both sides of the membrane.
The process of recycling dead cells is carried out by specialized cells called phagocytes. These cells engulf and break down the dead cells, recycling their components into new molecules that can be used by the body for energy or building new cells.

I believe that is fermentation.
When living cells break down food molecules, energy is released in the form of ATP (adenosine triphosphate). This process is known as cellular respiration and occurs in the mitochondria of the cell. ATP is the main energy currency of the cell and is used to power various cellular processes.

Fermentation causes cells to break down sugar into carbon dioxide and ethanol (alcohol) in the absence of oxygen. This process allows cells to generate energy by producing ATP through glycolysis.
Free radicals have a free reactive oxygen on its molecule that wants to bind to something so it can be stable. Radicals attach to your cells and 'steal' and break down the lipid membrane that holds your cells together. This causes the cells to lyse (leak) and eventually causes tissue damage. Reactive Oxygen Species (ROS) are molecules in our body that prevent this.

Enzymes are the special proteins that can break down large molecules into smaller molecules. These biological catalysts speed up chemical reactions in cells by lowering the activation energy required for the reaction to occur.
is when the immune system acts up and causes cells to break and cause hair loss
