What are the factors affecting respiration?
Factors affecting respiration – definition
- The process of respiration is influenced by a number of external and internal factors.
- The main external factors are temperature, light, oxygen supply, water supply, CO2 concentration, toxic and stimulating substances and disease and injury.
What are the two steps of aerobic respiration?
Steps of Aerobic Respiration
- Glycolysis. It is the primary step of aerobic respiration is glycolysis and takes place within the cytosol of the cell.
- Formation of Acetyl Coenzyme A. The second step in aerobic respiration is the formation of acetyl coenzyme A.
- Citric Acid Cycle.
- Electron Transport Chain.
What are examples of aerobic respiration?
When the breakdown of glucose food occurs with the use of oxygen ,it is called aerobic respiration. Glucose___oxygen _____co2 +water + energy. For example -Human ,dogs ,cats and all the animals and birds ,insects ,grasshopper etc many more and most of the plants carry out aerobic respiration by using oxygen of air.
What are three importance of respiratory system?
These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.
What causes increases and decreases in photosynthesis and cellular respiration?
the intensity of the light being absorbed by the chloroplasts. the concentration and availability of CO2 (Carbon Dioxide) the temperature.
What are the advantages and disadvantages of aerobic respiration?
Aerobic respiration also has advantages and disadvantages:
- Advantages: Aerobic respiration generates a large amount of ATP.
- Disadvantages: Aerobic respiration is relatively slow and requires oxygen.
What factors affect photosynthesis and cellular respiration?
We learned that light intensity, carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.
Which type of respiration is more efficient and why?
Answer. Aerobic respiration is more effective because aerobic respiration uses oxygen to break down glucose, amino acids and fatty acids and is the main way the body generates adenosine triphosphate (ATP), which supplies energy to the muscles.
Where does cellular respiration occur group of answer choices?
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals. Cellular respiration begins in the cytoplasm of cells. It is completed in mitochondria.
What is the three types of cellular respiration?
In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.
What type of reaction is cellular respiration and why?
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Some of this energy is converted to heat.
How do humans use aerobic respiration?
Aerobic respiration is the process by which many cells, including our own, produce energy using food and oxygen. It also gives rise to carbon dioxide, which our bodies must then get rid of.
What is the importance of aerobic respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can split glucose into just two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
What is process fuel in cellular respiration?
During glycolysis, a glucose molecule is cleaved in two, creating two pyruvate molecules and the energy molecule, ATP. The pyruvate molecules are shuttled quickly into the mitochondria, where they are used in the remainder of the respiration process. The glucose molecule is the primary fuel for cellular respiration.
What organisms perform cellular respiration?
Oxygen is required for cellular respiration and is used to break down nutrients, like sugar, to generate ATP (energy) and carbon dioxide and water (waste). Organisms from all kingdoms of life, including bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.
Why is cellular respiration more efficient when oxygen is present in cells?
Though cellular respiration can occur anaerobically without oxygen, the process is much more efficient under aerobic conditions, in the presence of oxygen. And what exactly is the role of oxygen? Oxygen is the final electron acceptor of the electron transport chain in the final step of cellular respiration.
What is the main purpose of cellular respiration?
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
What are the 3 main types of cellular respiration?
The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport. Figure below gives an overview of these three stages, which are also described below. Cellular respiration takes place in the stages shown here.
What are the main steps in aerobic respiration?
Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.
What is the primary fuel for cellular respiration?
GLUCOSE
How does pH affect respiration?
Explanation: Enzymes play a large part in respiration as it helps to catalyse the reaction. Enzymes are affected greatly by pH. This means that when the pH is greater than the optimum, the enzyme will be denatured and no longer be able to catalyse the reaction.
Which type of cellular respiration is more efficient?
Aerobic cell respiration
