Dr. Hodges notes that David's exhaled carbon dioxide levels are elevated. List all the metabolic pathways that function to synth
Mrrafil [7]

Answer:

Explanation:

The production of ATPs for skeletal muscle contraction  depends on the conditions that the muscles are exposed to.

In presence of abundant oxygen, to the cells  Aerobic respiration-cellular respiration is the most ideal. 32 ATPs and 4 C02 are produced as by-products during the process as by products majorly two C02 from each  of the 2 acetyl Co A that enters the  kerb's cycle.

Likewise direct phosphoryaltion of ADP to ATP gives 32.0 kj/mol of heat liberated but no C02 was produced. This takes place during chemiosmosis. with 28ATPs produced.

In absence of oxygen, anaerobic respiration of skeletal muscles produced ATPs  from  glycolysis, heat and  2C<u>02 as products, but not as by-product</u>.Through alcoholic fermentation pathway.

Therefore ,the correct answer is Aerobic respiration, because it gives out C02 which is a by-product, released out of the body as waste from the lungs,and not use up  in  the body.

During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the s
matrenka [14]

Answer and explanation:

Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.

These hormones have many functions and they all work together to prepare the individual for a fight or flight response -<em> like increasing heart rate and producing bronchodilatation</em>. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.

When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.

Which of the following statements are true for both the recrystallization and replacement modes of preservation? Choose one or m
vladimir2022 [97]

A similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.

<h3>What are recrystallization and replacement modes of preservation?</h3>

Recrystallization is a mode of preservation of fossils in which the internal structure of the fossils is changed by addition of more minerals to form larger crystal of the same material.

Replacement is a mode of preservation in which new material replaces the original material in the fossil.

In both methods of preservation, delicate tissue and organs are not preserved.

Therefore, a similarity in both recrystallization and replacement modes of preservation is that delicate tissue and organs are not preserved.
