The bonds connecting atoms in molecules contain energy. Chemical reactions involve the breaking of bonds in the input (reactant) molecules and the formation of bonds in the output (product) molecules. Energy is used in order to break bonds during reactions. Energy is released as bonds are formed during reactions. Energy can be measured using the unit kilocalories (kcal).
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.

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
