Answer:

Option d. 2615.0g

Explanation:

Let M1, M2, and M3 represent the masses of the three different samples

M1 = 0.1568934 kg = 156.8934g

M2 = 1.215mg = 1.215x10^-3 = 0.001215g

M3 = 2458.1g

Total Mass = M1 + M2 + M3

Total Mass = 156.8934 + 0.001215 + 2458.1

Total Mass = 2614.994651g

Total Mass = 2615.0g

Cellular respiration uses glucose and oxygen, which have high levels of free energy, and releases carbon dioxide and water, whic
Alja [10]

Answer: Cellular respiration is spontaneous and exergonic. The energy released from the glucose is stored in ATP molelcules.

Explanation:

Spontaneous reactions have an increase in entropy (level of disorder) and a decrease in enthalpy (total energy). Cellular respiration goes from a more ordered state (one molecule of glucose) to a more disordered state (several molecules of CO2), and goes from a state with a lot of free energy to one with much less free energy. As a result, respiration is a spontaneous process.

As free energy from the glucose is released as ATP molecules during oxidation, the reaction is exergonic.
