Which of the following is associated with the H+ proton?    a. Acts as a buffer against changes to muscle pH   b. Accumulation impairs calcium handling by the sarcoplasmic reticulum (SR)   c. Necessary molecule for the re-synthesis of ATP within the mitochondria   d. All of the above   e. Both B and C are correct

What sort of cellular changes would you expect a sailor sick with scurvy to experience? O Their collagen (an extracellular matrix component) would be diminished, resulting in fewer binding sites for integrins. The end result would be less adherent cells. O Their collagen (a cytoskeletal fiber) would be diminished, resulting in a loss of contractile motion within the cell, affecting both cell migration and muscle function.

The glycolytic system by which muscles obtain ATP…

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.
