Which part of the breakdown of glucose requires molecular oxygen O2?

The aerobic respiration process, which occurs in the mitochondria of cells, requires molecular oxygen (O2) to fully break down glucose into ATP (energy). This includes the Krebs cycle and the electron transport chain. If oxygen is not present, cells can undergo anaerobic respiration, which is less efficient.


Where does the oxygen atom for the formation of the water come from in Aerobic respiration?

In aerobic respiration, the oxygen atom used for the formation of water comes from molecular oxygen (O₂) that organisms inhale or absorb from their environment. During the process of cellular respiration, oxygen is utilized in the electron transport chain to accept electrons, ultimately combining with protons (H⁺ ions) to form water (H₂O) as a byproduct. This process occurs primarily in the mitochondria of cells.


How does the process of fermentation differ from the process of respiration?

while respiration implies air, fermentation is an anaerobic (no oxygen) process.


Does aerobic respiration refer to having oxygen or lacking oxygen?

Aerobic respiration refers to the process of producing energy using oxygen. It is a type of cellular respiration that occurs in the presence of oxygen.


In which process the amount of carbon dioxide is increase and in which process the amount of oxygen in air is decrease?

The amount of carbon dioxide in the atmosphere increases primarily through processes such as combustion, respiration, and deforestation. During cellular respiration, organisms convert glucose and oxygen into energy, producing carbon dioxide as a byproduct. Simultaneously, the amount of oxygen in the air decreases during respiration and combustion, as oxygen is consumed in these processes. Additionally, deforestation reduces the number of trees that produce oxygen through photosynthesis, further contributing to the decrease in atmospheric oxygen levels.

Which process uses oxygen in plants algae and animals?

For starters, algae are plants. Plants never use oxygen. Animals use oxygen in the process of respiration. Decomposers use oxygen in the process of respiration when decomposing plants and animals including algae.


Where does oxygen diffuse into the blood during the process of respiration?

Oxygen diffuses into the blood from the air sacs in the lungs during the process of respiration.


In which process is oxygen by an organism?

Respiration.


What is oxygen in its non molecular form?

Oxygen in its non-molecular form exists as an oxygen atom, denoted as O. It is a highly reactive element that can combine with other elements to form various compounds. Oxygen atoms freely exist in the Earth's atmosphere and play a crucial role in supporting life through the process of respiration.


What substance is removed from the air by living things for respiration?

In the process of respiration OXYGEN is taken in from the atmoshpere and CO2 is released.
