What is the difference between saturated and unsaturated hydrocarbons?
In saturated hydrocarbons, there are only single bonds between the carbon atoms. Unsaturated hydrocarbons contain at least one double or triple bond between carbon atoms.
What role does energy play in the cycle of photosynthesis and cellular respiration?
Light energy is absorbed during photosynthesis. This energy is converted to chemical energy and stored in the covalent bonds of carbohydrates. During cellular respiration, as the chemical bonds are broken, the energy is released as heat
