If not, describe the fate of O2 and the production of CO2.What products are formed during respiration? Glucose and Oxygen Water and Carbon Dioxide Water and Glucose Water and OxygenList the four processes of respiration, in order, for moving oxygen from the atmosphere to the body’s tissues. List, in order, the processes for the movement of carbon dioxide
- Which of the following are produced during cellular respiration? carbon dioxide, water, and ATP ATP and water carbon dioxide and ATP oxygen and glucoseWhat is the main difference between aerobic and anaerobic respiration?Which of the following statements about oxygen transport is TRUE. Increases in temperature and decreases in pH cause myoglobin to release oxygen to improve delivery to the hemoglobin in muscles. A molecule of myoglobin has higher oxygen binding capacity than a molecule of hemoglobin. Myoglobin has a higher oxygen affinity than does hemoglobin. Fetal hemoglobin has a lower affinity for oxygen than maternal hemoglobin, which makes it better suited to extract oxygen from the maternal circulation.
