metabolism

Examples of metabolism in the following topics:

• Human Metabolism

  • Metabolism in humans is the conversion of food into energy, which is then used by the body to perform activities.
  • The body metabolizes all the food we consume.
  • The body stores fat or metabolizes it only if energy intake changes for a period of several days.
  • The body adjusts its basal metabolic rate to compensate (partially) for over-eating or under-eating.
  • (a) The first law of thermodynamics applied to metabolism.

• Humans: Work, Energy, and Power

  • The rate at which the body uses food energy to sustain life and to do different activities is called the metabolic rate.
  • The total energy conversion rate of a person at rest is called the basal metabolic rate (BMR) and is divided among various systems in the body.
  • Identify what factors play a role in basal metabolic rate (BMR)

• Thermal Pollution

  • An increased metabolic rate may result in fewer resources; the more adapted organisms moving in may have an advantage over organisms that are not used to the warmer temperature.

• Blood Flow

  • The cardiovascular system, which consists of blood vessels and the heart, helps to distribute nutrients, O2, and other products of metabolism.

• Other Forms of Energy

  • When your body digests and metabolizes food it utilizes its chemical energy.

• Emission Topography

  • PET scans are increasingly read alongside CT or magnetic resonance imaging (MRI) scans, with the combination giving both anatomic and metabolic information.

• Ultraviolet Light

  • It has regulatory roles in calcium metabolism (which is vital for normal functioning of the nervous system, as well as for bone growth and maintenance of bone density), immunity, cell proliferation, insulin secretion, and blood pressure.
