<span>If heat is consumed during a reaction, the reaction is said to be an endothermic reaction.
There are two types of reactions related to heat energy, these are endothermic and exothermic </span>reactions.
Exothermic reactions are when the reactions as it proceeds gives out heat energy to the surroundings. Endothermic reactions are when heat energy is absorbed by the reactants to initiate and continue the reaction. Therefore reaction system absorbs or consumes heat energy from the surrounding.
The daughter isotope (a decay product)of O-15 = N-15(Nitrogen 15)
<h3>Further explanation
</h3>
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles γ
- positron particles ₁e⁰
O-15 emits positron particles ₁e⁰, so the atomic number decreases by 1, the mass number is the same
Reaction
The mass number of the daughter isotope = 15, atomic number = 7
If we look at the periodic system, the element with atomic number 7 is Nitrogen (N)
Answer:
In cellular respiration, cells use <u>oxygen</u> to release energy stored in <u>glucose</u>.
