Respiration involves respiration involves a photochemical reaction involving carbon dioxide and water to produce carbohydrates and oxygen. the use of heat energy to react carbon dioxide with water to produce oxygen. a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy. a photochemical reaction involving carbon dioxide and oxygen to produce water and oxygen.

The correct option is: a chemical reaction between carbohydrates and oxygen to produce carbon dioxide, water, and heat energy

Explanation:

Respiration refers to the catabolic reactions in the cells that produce energy in the form of adenosine triphosphate (ATP) from various nutrients.

An aerobic respiration, is a spontaneous process that involves the use of molecular oxygen (O₂) to produce energy (ATP). In this process, molecular oxygen oxidizes nutrients such as carbohydrates, fats, and proteins; to give carbon dioxide, water and heat energy.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
