Into which molecule are all the carbon atoms in glucose ultimately incorporated during cellular respiration?
pav-90 [236]

Answer:

The correct option is: carbon dioxide (CO₂)

Explanation:

Cellular respiration refers to the process of generation of energy in the form of adenosine triphosphate (ATP) from various nutrients such as carbohydrates, fats, and proteins.

Aerobic cellular respiration involves the oxidation of nutrients such as glucose (C₆H₁₂O₆), by molecular oxygen (O₂) to give carbon dioxide (CO₂), water (H₂O) and heat energy.

Reaction involved: (glucose) C₆H₁₂O₆ (s) + 6 O₂ (g) → 6 CO₂ (g) + 6 H₂O (l) + heat energy

<u>Therefore, in a cellular respiration, all the carbon atoms of the glucose molecules, form carbon dioxide.</u>

When heat energy is removed, two changes are observed:
Softa [21]

Answer: A is condensation and B is freezing.

The process in which the gas changes to the liquid phase due to the removal of heat is known as condensation. Rains are formed in this way. The water vapour rises. As it raises above it loses heat and then cools down and condenses and comes down as rainfall.

The process in which the liquid changes to a solid on removal of heat is known as freezing. Formation of ice is an example. When the heat is removed at -4 degree Celsius the water freezes to ice.

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions.
Norma-Jean [14]

2 KHP(aq) + Ba(OH)_{2}(aq) ---> KP_{2}Ba (aq) + 2 H_{2}O (l)\

Moles of Ba(OH)_{2}=0.483 \frac{mol}{L} * 28.5 mL *\frac{1 L}{1000mL}  = 0.0138 mol Ba(OH)_{2}

Mass of KHP = 0.0138 mol Ba(OH)_{2} * \frac{2 mol KHP}{1 mol Ba(OH)_{2}}  * \frac{204.22 g KHP}{1mol KHP}

= 5.64 g KHP
