Answer:
c. Less oxygen consumption per second
Explanation:
- The sarcomere is a functional unit of muscle tissue. During repeated muscle contractions, the oxygen delivery to the muscle is reduced.
- As noted in the question, the rate and load of muscle contractions are the same under both conditions but the differences in the number of contractions in the second day experiment only increase.
- So as the number of contractions increases, more time is required to work. But continuous work can lead to a shortage of oxygen. Therefore, due to low availability, less oxygen per second is consumed. Lactic acid production by anaerobic respiration through muscle tissue causes muscle fatigue.
- Considering other dubious options, there is no increase in load and there is not much power generation. At the same time, ATP consumption increases due to continuous contraction, so the cellular ATP / ADP ratio is generally reduced.
- Since the calcium release by the sarcomere is reduced during continuous muscle contraction and the contraction rate does not change, the cross-bridge cycling speed is not affected.
For Anna’s case, my preliminary idea of the species of bacteria
responsible for Anna’s infection is a Gram-negative bacterium as observed in gross examination of the
colony. With this, my <span>idea has not changed since the last activity for the bacteria was
rod-shaped when we view it through a
microscope and the color of the colonies was
pink after we Gram stained it, which indicate that it is Gram-negative.</span>
