The energy required to break apart glucose and oxygen during cellular respiration is 2,878 kcal. The energy released during the formation of carbon dioxide and water during cellular respiration is 3,564 kcal. Identify whether cellular respiration requires a net input of energy or if the reaction results in a net release of energy. Use mathematical evidence to support your response.

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. a physical change doesn’t break the bonds between atoms of a substance or form new ones. compounds can be broken down by a chemical change. a chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. what simple substance would a compound break into? the basic elements that make it up! for example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. which of the following is an example of a chemical change? a separating water into different glasses b breaking frozen ice cubes with a hammer c running an electric current through water d boiling water to evaporate it on a stove
