RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which substances do cells in the human body need to carry out cellular respiration?
A
oxygen and water
B
oxygen and carbon dioxide
C
glucose and sunlight
D
oxygen and glucose
Explanation: 

Detailed explanation-1: -During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP.

Detailed explanation-2: -Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Detailed explanation-3: -Most of cellular respiration takes place in sausage-shaped organelles called mitochondria. Although mitochondria play a key role in other cellular processes, their main function is to produce large amounts of energy through cellular respiration.

Detailed explanation-4: -Cells need oxygen for the efficient use of glucose in cellular respiration. Most organisms use this method to obtain energy. Oxygen binds to parts of glucose molecules, which release water, carbon dioxide, and energy. After all, this is done, the organism uses the energy to produce adenosine triphosphate (ATP).

Detailed explanation-5: -Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.
