Answer
The release of stored potential energy in organic compounds during cellular respiration is a controlled process that captures energy in the form of ATP, while combustion is a rapid, uncontrolled reaction that releases energy as heat and light.
Solution
a
Controlled Release of Energy: Cellular respiration is a biochemical process that breaks down organic molecules in a controlled manner to produce ATP, the energy currency of the cell
b
Uncontrolled Release of Energy: Combustion is a chemical reaction between a fuel and an oxidant, producing heat and light. It occurs rapidly and releases energy in an uncontrolled manner
c
Efficiency: Cellular respiration captures energy efficiently, with approximately 40% of the energy from glucose converted into ATP, while the rest is lost as heat. Combustion converts energy into heat and light, with no energy capture for biological work
d
Byproducts: The byproducts of cellular respiration are carbon dioxide and water, which are less harmful and can be used in other biological processes. Combustion produces carbon dioxide, water, and potentially other harmful pollutants

Explanation
Cellular respiration is a controlled process that efficiently captures energy for cellular use, while combustion is a rapid, uncontrolled reaction that releases energy primarily as heat and light.
