- It is essential for the cells in plants and animals to have an adequate supply of oxygen. Explain what the oxygen is needed for in the cells? (Be as specific as possible.)On a nice cool day, you decided to take a deep breath in and breathe out and saw a fog that formed as a consequence of your exhaled breath.

- Which of the following statements correctly describes why white muscle fibers do not need is mini mitochondria as red muscle fibers? a) want muscle fibers use anaerobic respiration which does not occur in the mitochondria b) what muscle fibers use anaerobic respiration which requires more efficient mitochondria than aerobic respiration c) white muscle fibers get more oxygen than the red muscle fibersWhat is the difference between respiration and aerobic cellular respiration?In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.
- What is the physiological significance of aerobic cellular respiration?Practice concentration gradients: A) Active tissues generate carbon dioxide during cell respiration. This carbon dioxide diffuses out of the tissue into the bloodstream. 1) where is the higher concentration of carbon dioxide ? 2) is Carbon dioxide flowing down or against its concentration gradient ? 3) Is energy required for the movement of carbon dioxide ? Calculate concentration gradient solute 55M Solute 52MNitric oxide (NO) is a gaseous molecule with lipid solubility similar to that of O2 and CO2. Endothelial cells lining arteries use NO to signal surrounding smooth muscle cells to relax, thereby increasing blood flow. What mechanism or mechanisms would transport NO from where it is produced in the cytoplasm of an endothelial cell into the cytoplasm of a smooth muscle cell, where it acts?
