Cells need O2 every minute of the day/night. But exercise or strenuous activity place higher demands on O2 needs. For healthy persons, the cardiovascular system compensates during activity much easier than if a person is ill.

When the oxygen is carried to cells it is used to relese what?

cells use the oxygen to release chemical energy.


What cell is the process by which cells release energy without oxygen?

Anaerobic respiration is the process by which cells release energy without oxygen. This process occurs in the cytoplasm of cells and involves the breakdown of glucose into energy-rich molecules, such as ATP, in the absence of oxygen. Anaerobic respiration is less efficient than aerobic respiration but allows cells to continue producing energy when oxygen is limited.


Cells use oxygen and sugars during cellular respiration and release what?

energy, water and oxygen


What is the process in which glucose and oxygen react in cells to release energy?

inhaling


What does the delivery of oxygen to cells to do?

Oxygen is used by cells for the process of respiration. Respiration is the release of energy from food. When this happens using oxygen it is called aerobic respiration: glucose + oxygen ----> water + carbon dioxide + ENERGY IRON


What process requires oxygen to release energy?

The process that requires oxygen to release energy is cellular respiration. In this process, cells break down glucose in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate).


What is produced when cells use oxygen to release energy from sugar?

they form children


What chemical reaction in cells need oxygen to release energy?

The process that requires oxygen to release energy in cells is called cellular respiration. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the main energy source for cells.


When do cells use oxygen to release energy?

Cells use oxygen to release energy during cellular respiration, specifically in the final stage called the electron transport chain. Oxygen is the final electron acceptor in this process, allowing for the production of ATP, which is the cell's main source of energy. Without oxygen, cells cannot efficiently produce ATP through aerobic respiration.


When oxygen is carried to cells it used to release what?

When oxygen is carried to cells, it is used to release energy from glucose molecules through a process called cellular respiration. This process generates ATP, the energy currency of the cell, which is essential for various cellular functions and activities.


What does the delivery of oxygen allow cells to do?

Oxygen is used by cells for the process of respiration. Respiration is the release of energy from food. When this happens using oxygen it is called aerobic respiration: glucose + oxygen ----> water + carbon dioxide + ENERGY IRON
