Endothermic reactions ​ (a)   energy and exothermic reactions ​ (b)   energy.

• store

• release

Answer explanation

Endothermic reactions absorb or take in energy from their surroundings, hence the correct answer for the first blank is 'absorb'. On the other hand, exothermic reactions release energy into their surroundings, hence the correct answer for the second blank is 'release'.
