May be used to calculate the amount of energy expended by the body?
One can use the Harris-Benedict equation or the Mifflin-St Jeor equation to estimate the Basal Metabolic Rate (BMR), which represents the amount of energy the body expends at rest. From the BMR, other factors like activity level can be used to calculate total daily energy expenditure.
Does respiration use oxygen?
Yes, respiration is the process by which cells break down glucose to release energy. In aerobic respiration, oxygen is used as the final electron acceptor in the electron transport chain to produce ATP, the cell's main energy source. Oxygen is necessary for this process to efficiently generate energy.
What is used to calculate the amount of energy expended by the body?
When a person is placed on a treadmill and connected, by special breathing tubes, to measuring equipment it is the rate-of-consumption of Oxygen that is being examined. The amount of caloric consumption is also reflected by the [measured] rate of CO2 production and exhalation.
What is the nuclear binding energy of oxygen-16 given that 1 amu 1.6605x1027?
The mass of an oxygen-16 atom is approximately 16 amu. The mass of the individual protons, neutrons, and electrons that make up the atom is slightly less, due to the release of energy when they bond. The difference in mass between the individual particles and the oxygen-16 atom represents the nuclear binding energy.
Is oxygen a form of energy?
No, oxygen is not a form of energy itself. However, oxygen is necessary for most forms of energy production through processes like combustion and respiration where it helps release energy stored in other substances.
What may be used to calculate the amount of energy expended by the body?
Oxygen consumed
How many kilojoules are used for every one liter of oxygen consumed?
For every one litre of oxygen used, approximately 21 kJ (approximately 5Kcals) of energy is expended. Ref. Clinical Exercise Prescription, Fitness Institute Australia (c) 2008
What does a MET represent what does it measure?
A MET, or Metabolic Equivalent of Task, is a unit that measures the energy cost of physical activities as a multiple of resting metabolic rate. Specifically, 1 MET is defined as the energy expended while at rest, which is approximately 3.5 milliliters of oxygen consumed per kilogram of body weight per minute. MET values help quantify the intensity of various physical activities, allowing individuals to compare the energy expenditure of different exercises. For example, a task that requires 8 METs would use eight times the energy expended at rest.
How much oxygen is consumed in forming iron rust?
Technically, all of the oxygen in the air is consumed when forming iron rust. Air is approximately 20 percent oxygen, and that entire amount is consumed when forming iron rust.
What substance are produced and consumed in photosynthesis?
Oxygen+glucose are produced, CO2+water+ the energy from the sun light are consumed
What are two indicators that a combustion reaction has occurred?
energy is released and oxygen is consumed
Why is oxygen necessary as you exercise?
As muscles work harder and more energy is expended, oxygen demand rises. As a result, you breathe harder, increasing the rate and depth of respirations and, thus, take in more oxygen.
In which process is oxygen consumed?
Oxygen is consumed during the process of cellular respiration, which occurs in cells to produce energy in the form of ATP. In this process, glucose is broken down with the help of oxygen to release energy, carbon dioxide, and water.
What gases are produced and consumed during photosynthesis in plants?
carbon dioxide is consumed and oxygen is produced
Oxygen is consumed as a result of which type of change?
Oxygen is consumed in exothermic reactions where it combines with other elements to form oxides, such as combustion reactions. In these reactions, energy is released in the form of heat.
How does exchange of nutrients and oxygen with waste and carbon dioxide take place in the capillaries?
Pure diffusion ... everything flows from high concentration toward low. No energy is expended in these exchanges.
