Question 1(Multiple Choice Worth 4 points)

(04.03 MC)

Which of the following steps does not take place during cellular respiration?
Glucose is broken down.
Energy is transferred to cells.
Oxygen combines with carbon dioxide.
Energy and other products are released.

C: Oxygen combines with carbon dioxide.

Explanation:

Cellular respiration is a biological process, by which complex molecules, such as glucose is breakdown to produce energy in the form of ATP molecules.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
