Blood pH — a reflection of its relative acidity or alkalinity — also influences respiratory rate. Activity level and the presence of drugs or alcohol are other important factors that affect respiratory rate.
Light intensity. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide.
Carbon dioxide concentration.
Temperature.
Also question is, what are the factors that affect the rate of cellular respiration?
Aerobic cellular respiration rates vary according to three main factors: the amount of nutrients available to the cell, the specific type of cell and the ambient temperature. All three factors affect the rate at which respiration takes place.
What factors can limit the rate of respiration?
Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.
What affects the rate of aerobic respiration?
Here are some of the few factors that affect the rate of respiration. Carbon dioxide concentration: The higher the carbon dioxide concentration, the lower the rate of respiration. Increase in carbon dioxide concentration and absence of oxygen adversely affects the rate of aerobic respiration.
What factors can affect the rate of respiration?
The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.
What factors affect breathing?
Increased exertion increases respiration rate due to the increased metabolic demands of the body. With exertion the level of carbon dioxide in the blood increases due to increased cellular respiration by the muscles. During rest the level of carbon dioxide is lower, so breathing rate is lower.
What is the most important factor controlling the rate and depth of breathing?
The most important factor controlling the rate and depth of breathing is the effect of carbon dioxide on the central chemoreceptors. The hydrogen ions stimulate the central chemoreceptors, which send nerve impulses to the respiratory centers in the medulla.
What factors affect the respiratory rate?
Let’s see the factors affecting the rate of respiration.
Temperature: At a very high temperature, the rate of respiration decreases with time, and at very low temperature, the respiration rate is insignificant.
Carbon dioxide concentration: The higher the carbon dioxide concentration, the lower the rate of respiration.
How does exercise affect respiration rate?
Your heart speeds up to pump extra food and oxygen to the muscles. Breathing speeds up to get more oxygen and to get rid of more carbon dioxide. When a fit person, such as an athlete, exercises the pulse rate, breathing rate and lactic acid levels rise much less than they do in an unfit person.
What are the factors that can affect vital signs?
Several factors can cause changes in one or more of the vital signs: age, gender, heredity, race,lifestyle, environment, medications, pain, and other factors such as exercise and metabolism, anxiety and stress, postural In the elderly, the efficiency of thermoregulation is reduced by the physiological changes of aging,
What are the factors that affect the temperature?
Factors affecting climate
Latitude or distance from the equator. Temperatures drop the further an area is from the equator due to the curvature of the earth.
Altitude or height above sea level. Locations at a higher altitude have colder temperatures.
Distance from the sea.
Ocean currents.
Prevailing wind.
What causes an increase in respiratory rate?
A third paradigm is: tachypnea is abnormally rapid respiration (though some may argue this is inaccurate as breathing differs from respiration), hyperventilation is increased rate or depth of respiration to abnormal levels causing decreased levels of blood carbon dioxide and hyperpnea is any increase in breathing rate
What causes air to enter and exit the lungs?
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
What are the factors that affect the pulse rate?
How Other Factors Affect Heart Rate
Air temperature: When temperatures (and the humidity) soar, the heart pumps a little more blood, so your pulse rate may increase, but usually no more than five to 10 beats a minute.
Body position: Resting, sitting or standing, your pulse is usually the same.
What chemical factors affect breathing?
Emotional factors: Some emotional stimuli can modify breathing. Examples are fear, anger, and excitement. Chemical factors: Changes in blood levels of carbon dioxide are the most important stimuli affecting respiratory rhythm and depth. Carbon dioxide acts directly on the medulla via its effect on reducing blood pH.
How does hyperventilation decrease the respiratory rate?
Hyperventilation causes a fall in the body’s carbon dioxide. As a result, the amount of acid produced is decreased, leading to a rise in the body’s pH. This condition is known as alkalosis. Carbon dioxide acts on certain respiratory centers in the brain and normally stimulates breathing.
How does the medulla increase breathing rate?
The medulla oblongata detects the levels of oxygen and carbon dioxide concentrations and signals the muscles in the heart, the lungs and diaphragm to increase or decrease the breathing. The pons controls the speed of inhalation and exhalation or respiration rate depending on the need of the body.
What will happen to the respiratory rate when the temperature decreases?
When temperature increases, rate of respiration increases as well because the heat speeds up the reactions which means kinetic energy is higher. This means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow down.
How does exercise affect your breathing rate?
Some of the blood pumped by the heart travels to the lungs to get rid of carbon dioxide and pick up oxygen. The increase in heart rate stimulates your breathing rate. With an increase in heart rate, your blood pumps through your muscles at a faster rate, leaving less time for oxygen uptake.
What is the part of the brain that controls breathing?
The cerebrum, the cerebellum, and the spinal cord are all connected to the brainstem. The brainstem has three main parts, the midbrain, the pons, and the medulla oblongata. The brain stem controls vital functions of the body, including: Breathing.
What factors might affect the process of cellular respiration?
Many factors affect the rate of cellular respiration in living things.
Amount of Nutrients. The more nutrients that are available to transform, the more energy results in the cellular respiration process.
Temperature. Another factor affecting the cellular respiration is the temperature of the environment.
State of Cell.
How does temperature affect the rate of respiration in yeast?
When oxygen is present (aerobic respiration) yeast cells use enzymes to convert glucose to carbon dioxide and water, releasing lots of energy in the process. As the temperature rises the rate of cellular respiration increases as enzymes in yeast work better in warmer conditions.
Where does the respiration occur?
Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria.
How was respiration rate measured in respiration lab?
When you study the equation for cellular respiration, you will see that there are at least three ways: Measure the amount of glucose consumed. Measure the amount of oxygen consumed. Measure the amount of carbon dioxide produced.
