What is the correct order for aerobic cellular respiration?
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.
Where does cellular respiration happen?
Key Terms
| Term | Meaning |
|---|---|
| Mitochondria | The eukaryotic cell structure where cellular respiration occurs |
| Cytoplasm | The contents of a cell between the plasma membrane and the nuclear envelope; includes cytosol which is the jelly-like substance that fills the space between organelles |
| Aerobic | Process that requires oxygen |
What is an important similarity between photosynthesis and cellular respiration?
An important similarity between photosynthesis and cellular respiration is that both processes involve a chemical reaction where an energy source is taken and transformed into a resultant product.
What is the difference between the use of the terms cellular respiration and respiration in biology?
What is the difference between the use of the terms cellular respiration and respiration in biology? Cellular respiration refers only to the breakdown of energy-rich molecules to produce ATP; respiration can refer to breathing.
What is the relationship between the ETC and oxygen explain?
Explanation: Oxygen acts as the terminal electron acceptor in the electron transport chain (ETC). This accounts for the reason as to why, when cells are starved of oxygen, the ETC “backs up” and the cell will divert to using anaerobic respiration, such as fermentation.
What is the connection between the electron transport chain and oxygen?
Oxygen sits at the end of the electron transport chain, where it accepts electrons and picks up protons to form water.
Why oxygen is important to the process of cellular respiration?
Cellular respiration is the cellular process which transfers chemical energy from glucose to ATP. Oxygen is essential to have efficient cellular respiration; most organisms need oxygen for a single purpose: to release energy from food for use by cells.
What role does the circulatory system play in aerobic cellular respiration select two answers that are correct?
What roles does the circulatory system play in aerobic cellular respiration? Select the TWO answers that are correct. 1) transport oxygen to body tissues and carbon dioxide to the lungs. The citric acid cycle and electron transport are not used in anaerobic respiration.
What is the relationship between the circulatory system and cellular respiration?
The circulatory system also transports oxygen from the lungs to the cells. Now the cells have what they need for cellular respiration: oxygen and glucose. The teamwork doesn’t end there, however. The circulatory system also transports carbon dioxide waste from the cells to the lungs of the respiratory system.
What is the connection between the respiratory system the circulatory system and cellular respiration?
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body cells.
How does the digestive system contribute to cellular respiration?
The digestive system breaks down the food into molecules. The cells then convert those molecules into a form of energy they can use. So how do plants and animals convert those food molecules into a form of energy they can use? Through a chemical process called cellular respiration.
