Add to this diagram and explain why a cell needs to constantly break down atp to make atp

Anything that the cell does require energy also known as ATP so the process of breaking down ATP uses ATP and vice versa

The correct answer is: b).

Explanation:

Oil or solid fat is composed of long chains made up of hydrocarbons (fatty acids).The fatty acid can be:Saturated - in which all the carbon atoms in the long hydrocarbon chain are linked to each other by single bonds. As a result of this there is a tight packing between the fatty acid molecules which gives them a solid texture at room temperature.Unsaturated - in which there are one or more double or triple bonds in between carbon atoms in the long hydrocarbon chain. As a result of this kinks or bends develop in the fatty acid chain which results in generation of space or gap in between fatty acid chains. This gives the fatty acid the capability to move as a result of which they have a liquid texture at room temperature.Hydrogenation is a process by which the unsaturated fatty acids (oil) are converted to saturated fatty acid (margarine) by reducing the multiple bonds in between the carbon atoms with hydrogen.Hydrogenated oil has a higher melting point and so it is solid at room temperature.Hydrogenated oil can also cause clogging in the arteries as they cannot be easily broken down due to their increased stability.
