O
Explanation:
Oxygen is a more reactive non-metal.
There are several parameters to test how reactive an element is. In this case, we are going to use the electronegativity of the two atoms.
- Electronegativity is the relative tendency with which atoms of the element attract valence electrons in a chemical bond.
A high electronegativity value suggests more reactivity and a low value implies low reactivity.
On the Pauling's Eelectronegativity table, Oxygen has a value of 3.5 and Phosphorus has 2.1
It implies that oxygen is a more reactive non-metal compared to phosphorus.

It’s mass number would be 5 as it’s the protons and the neutrons added together
Reduction I think... not entirely sure though... when a molecule loses oxygen...?
Food is made up of organic (carbon-containing) molecules that contain chemical bonds between their atoms that act as energy storage units. In addition to using the energy in food to fuel life processes, organisms construct larger organic molecules, such as proteins, DNA, and fats (lipids), using the atoms from food molecules.
What is glucose ?
The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.

The correct answer is option 4. The conversion of energy is from chemical to electrical energy. Voltaic cells are driven by a spontaneous reaction that produces an electric current. Voltaic cells are a type of electrochemical cell.
