Answer:
<h3>The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle). The electron transport chain takes place in the mitochondria.</h3>
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.
Cytokinesis is when the cell pinches in 2 towards the end of meiosis and mitosis divisions. The chromsomes aren't as spread out and easy to see as during metaphase.
Meiosis is the whole process of producing gametes and not a stage/phase of division.
Mitosis is the whole process of cell division for growth and repair.
Metaphase is a particular phase in mitosis and meiosis where the chromosomes have been duplicated and are contracted and visible.
