The rate of respiration is determined by what levels in the blood?
The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.
What is the rate of respiration determined by levels in blood?
The rate of respiration is determined by the levels of oxygen and carbon dioxide in the blood. The main controller of the rate of respiration is the brain.
How are oxygen levels affected by respiration?
During respiration, oxygen levels decrease as it is consumed by cells to produce energy in the form of ATP through the process of cellular respiration. As cells use oxygen to break down glucose or other nutrients, it combines with hydrogen to form water, carbon dioxide, and ATP. The carbon dioxide produced is then expelled by the body during expiration.
Where is the secondary respiratory center found?
The secondary respiratory center is found in the medulla oblongata, which is part of the brainstem. It helps regulate respiration in response to changes in blood pH, oxygen levels, and carbon dioxide levels.
How is respiration dependent on chemical factors in the blood?
Respiration is closely regulated by chemical factors in the blood, primarily the levels of carbon dioxide (CO2), oxygen (O2), and pH. Increased CO2 levels lead to a decrease in blood pH, stimulating chemoreceptors to signal the respiratory center in the brain to increase the rate and depth of breathing, enhancing CO2 elimination. Conversely, low oxygen levels can also trigger increased respiration to improve oxygen intake. This intricate feedback mechanism ensures that the body maintains homeostasis and meets its metabolic demands.
Respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere?
fairly constant
How are oxygen and carbon dioxide levels maintained?
Oxygen and carbon dioxide levels are maintained through the processes of photosynthesis and respiration in living organisms. During photosynthesis, plants and certain bacteria take in carbon dioxide and release oxygen, helping to increase oxygen levels and decrease carbon dioxide levels. Conversely, during respiration, organisms take in oxygen and release carbon dioxide, balancing the levels of both gases in the atmosphere.
Which two processes are responsible for keeping the percentage of atomospheric oxygen at relatively constant levels?
Photosynthesis and respiration are the two processes that help to maintain the percentage of atmospheric oxygen at relatively constant levels. Photosynthesis by plants and other organisms produces oxygen, while respiration by animals and other organisms consumes oxygen. The balance between these two processes helps keep atmospheric oxygen levels stable.
What two processes are responsible for keeping the percentage of atmospheric oxygen at relatively constant levels?
Photosynthesis by plants and phytoplankton, and respiration by living organisms help maintain the percentage of atmospheric oxygen at relatively constant levels. Photosynthesis produces oxygen as a byproduct, while respiration consumes oxygen but also releases it back into the atmosphere.
Respiration with and without oxygen is called?
Aerobic respiration requires oxygen; anaerobic respiration does not use oxygen.
In which situation does anaerobic respiration take place in?
When the body doesn't have the physical strength to maintain the oxygen levels needed for aerobic respiration. As a result of this, lactic acid will be produced.
Photosynthesis and respiration keep levels of oxygen and CO2 at equilibrium?
Photosynthesis occurs in plants and some bacteria. It occurs within the chloroplasts. It uses H2O, Light energy and CO2 and gives off O2 and glucose. Respiration occurs in plants and animals. It occurs within the mitochondria. It uses O2 and glucose to produce energy, CO2 and H2O
