Question

Define: Cellular respiration.​

Answer 1

Answer:

cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Answer 2

• Cellular respiration is a set of metabolic actions and processes that take place inside the cells of animals to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP) and then release waste products.
• Catabolic reactions split large molecules into smaller ones, releasing energy when weak high-energy connections, such as those present in molecular oxygen, are replaced by stronger bonds in the products.
• Respiration is one of the most fundamental ways for a cell to release chemical energy in order to maintain its activities.
• The whole reaction is made up of a number of biological phases, including several redox reactions.
• Despite the fact that, in the strictest sense, cellular respiration is a combustion reaction.
