what is the relationship between respiration and temperature?

The amount of respiration exhibited by leaves and whole plants at any temperature is influenced by the pretreatment temperature. Plants grown at 10°C typically show higher dark respiration rates than plants grown at 20°C.

Temperature is the average kinetic energy of the particles. All particles are vibrating, and this is kinetic energy. Internal energy is the sum of the kinetic energy and potential energy stored in a system. Heat is is thermal energy being transferred because of a difference in temperature.

Active absorption requires input of energy, which is obtained from cellular respiration. Respiration is an enzymatic process and is inhibited at extreme temperatures. Hence, the optimum temperature for active absorption is twenty to thirty five degree celsius.

Charles' Law: The Temperature-Volume Law. This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. As the volume goes up, the temperature also goes up, and vice-versa.

Respiration is considered as an exothermic reaction because it involves reaction of glucose and oxygen and gives out energy. most of energy is stored in ATP molecules while some energy is lost in the former of heat which maintains the constant temperature of our body.

Temperature is directly proportional to pressure, so the lower the pressure, the lower the temperature. In short, the higher the altitude, the lower the temperature. The temperater drops at the standard lapse rate of about a degree and a half per 1000 feet of altitude.

There is a difference between Respiration and Breathing. Breathing is taking in Oxygen and giving out Carbon dioxide, whereas Respiration is a process in which Food molecules are broken down in presence of oxygen to liberate the energy in the form of ATP.

All organisms respire in order to release energy to fuel their living processes. The respiration can be aerobic, which uses glucose and oxygen, or anaerobic which uses only glucose.

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. ... Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

As the pressure decreases with altitude, the parcel of air expands against the reduced external pressure. It does work in doing so, which reduces its internal energy, the average energy of its constituent molecules. The definition of temperature is molecular kinetic energy. When this is lower, temperature is lower.

But respiration is the process in energy is produced while inhaling and exhaling. They are not the same, because respiration is the breaking down of food in simpler substance with the help of oxygen and breathing is the process of taking in oxygen .

What is the difference between cellular respiration and breathing (respiration)? Respiration (breathing) is the way your body gets oxygen into the lungs from the air outside. Cellular respiration describes how your cells make ATP - a molecule used to provide energy for chemical reactions.

The relationship between the two is that air temperature changes the air pressure. For example, as the air warms up the molecules in the air become more active and they use up more individual space even though there is the same number of molecules. This causes an increase in the air pressure.

Respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. Carbon dioxide and water are formed as by-products of respiration (Figure 4).

Heat is the sum of all the kinetic energies of all the molecules of an object, while temperature is the average kinetic energy of the molecules of an object.

Effect of Temperature on Enzyme Action. Temperature affects the reaction rate of enzymes, as do pH, substrate concentration and enzyme concentration. At low temperatures, enzymes have low activity. As the temperature rises the rate of reaction increases, usually 2-fold for every 10 degree Celsius rise.

External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs. Internal respiration is the exchange of gases with the internal environment, and occurs in the tissues.
