Answer:

C.In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

Explanation:

C. In the absence of oxygen, creatine phosphate can drive aerobic respiration pathways for a few minutes.

This statement  not true for a following reasons.

Firstly,  creatine phosphate directly phosphorylates ATP instead of providing any support for aerobic pathways.

Secondly, creatine phosphate stores are used up in about 15 seconds only. Thirdly, a cell does not need  oxygen deficit for creatine phosphate to be activated, it just needs to be short on ATP.

1. do you think erythropoietin levels in athletes at low altitude are lower, higher, or the same after training at a high altitu
den301095 [7]

1. Erythropoietin will be higher at low   altitude. Erythropoietin or EPO level will be higher because of the raised blood oxygen training but its lasting period will depend on the training content as here it is only 2 months.

About high erythropoietin:

Among the objectives of altitude training is to improve athletes' sea-level endurance performance by raising blood oxygen carrying capacity. The attainment of improved haematological variables is mostly due to the augmented erythropoietin (EPO) production in hypoxia. The duration of exposure and degree of hypoxia affect the level of the erythropoietin EPO rise and the rate of erythropoiesis acceleration. The haematological response to altitude training may also be influenced by a wide range of additional factors.

2. 100 ml of blood contain 27.8 mL of oxygen. This can be said as it has been shown that a healthy person typically possesses 20 grammes of haemoglobin in every 100 millilitres of blood.

Procedure:

=20∗1.39

=27.8mL

Amount of oxygen found in 11 grams of hemoglobin is equal to 1.39 milliliters of oxygen.

Thus, the total amount of oxygen in milliliters would be equal to product of total weight of hemoglobin and the total amount of oxygen in ml in one gram of hemoglobin.

3. Athletes training at high altitude have more oxygen molecules. They have an advantage as a result of having more red blood

Why so:

Higher elevations have thinner air, which has less oxygen molecules per volume of air. The body therefore makes more red blood cells when athletes workout at these high elevations. For up to 20 days, these additional blood cells remain in the body. Also as a result of having more red blood cells, their blood can carry more oxygen. When they compete at lower elevations, their muscles naturally get a boost from more oxygen.
