Why internal respiration is also called cellular respiration?
Answer: Internal respiration refers to gas exchange across the respiratory membrane in the metabolizing tissues, like your skeletal muscles. It is also called as cellular respiration as oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
What is internal respiration also known as?
Cellular respiration or internal respiration is a chemical process in which food molecules are broken down into simpler molecules within the cells and energy is produced. Enzymes take part in the process of cellular respiration.
Is cellular respiration internal or external?
External respiration is the breathing process. It involves inhalation and exhalation of gases. Internal respiration involves gas exchange between the blood and body cells. Cellular respiration involves the conversion of food to energy.
What is meant by cellular respiration?
cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
In which cell does cellular respiration occur?
mitochondria
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
What is the difference between internal respiration and external respiration and cellular respiration?
External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.
What is another word for cellular respiration?
n. metabolic process, metabolism.
What are the two types of cellular respiration?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
Which type of cell does not do cellular respiration?
If the cell cannot catabolize the pyruvate molecules further, it will harvest only two ATP molecules from one molecule of glucose. Mature mammalian red blood cells are not capable of aerobic respiration—the process in which organisms convert energy in the presence of oxygen—and glycolysis is their sole source of ATP.
What are the major differences and similarities between internal and external respiration?
The main difference between internal respiration and external respiration is that internal respiration refers to the gas exchange across the respiratory membrane in the metabolizing tissues whereas external respiration refers to the gas exchange across the respiratory membrane of lungs.
Is cellular respiration another word for breathing?
In our lungs, respiration can refer to the act of breathing. Cellular respiration is a chemical process that takes place inside cells and produces energy.
What is the opposite of cellular respiration?
Cellular respiration and photosynthesis are direct opposite reactions Cellular respiration and photosynthesis are direct opposite reactions. Energy from the sun enters a plant and is converted into glucose during photosynthesis.
