What is the relationship between oxygen and respiration?

Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). 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. In cellular respiration, glucose and oxygen react to form ATP.

What is the relationship between breathing rate and cellular respiration rate?

the breathing rate and volume of each breath increases to bring more oxygen into the body and remove the carbon dioxide produced. the heart rate increases, to supply the muscles with extra oxygen and remove the carbon dioxide produced.

What is the rate of oxygen uptake?

Humans use this oxygen to extract approximately 2550 Calories (10.4 MJ for a 70 kg, 20 y old male [5]) from food to meet daily energy requirements. This combustion requires approximately 22 moles of dioxygen per day, or 2.5 × 10-4 mol s-1. For a 70 kg person, this rate of O2-uptake is 3.6 × 10-9 mol s-1 g-1.

What is the relationship between rate of breathing oxygen and the body’s need for energy?

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. Breaking down sugar produces the energy your body needs.

What is difference between breathing and respiration?

Breathing and respiration are two completely different but interrelated body processes which assist body organs to function properly. Breathing is the physical process of exchanging gases whilst respiration is a chemical process which takes place at a cellular level and produces energy.

How are circulation and respiration related?

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

What is the relationship between respiration and activity?

During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise. The rate and depth of breathing increases – this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.

What is the relationship between exercise breathing rate and heart rate?

Breathing rate increases to provide the body (exercising muscles) with oxygen at a higher rate. Heart rate increases to deliver the oxygen (and glucose) to the respiring muscles more efficiently. The heart, lungs and circulatory system working together make up the cardiovascular system.

What determines overall oxygen uptake?

Rates of oxygen uptake during submaximal exercise will depend on gait, economy of locomotion, body mass, and other factors. The maximal rate of oxygen uptake is the gold standard measurement for aerobic capacity. It is primarily limited by the maximal heart rate and cardiac stroke volume during exercise.

What is oxygen uptake?

Oxygen uptake (or consumption) is a measure of a person’s ability to take in oxygen and deliver it to the working tissues, and the ability of working tissues to use oxygen. This anaerobic contribution to the total energy cost of exercise is termed the oxygen deficit (83, 107).

What happens to the rate of breathing during exercise and why?

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.

What are the similarities between respiration and breathing?

Both processes involve taking in oxygen and removing carbon dioxide, and we need both to survive. However, breathing is a macroscopic process and only ships the oxygen and carbon dioxide around the body. Cellular respiration is a microscopic process, taking place in the cells.
