The correct answer is - 19 ATP.

Explanation:

One molecule of dihydroxyacetone phosphate fully oxidizes and generate 19 molecules of ATP by the following stochiometry

Direct ATP- 2

ATP from NADH ( 5X3)= 15

ATP from GTP 1

maksim [4K]

Answer:

The presence of air in the pleural cavity

Explanation:

A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.

Phoenix [80]

Answer:

SER, they are capable of synthesizing testosterone of Adrenocortical cells.

Explanation:

Adrenal smooth microsomal cells are  enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.

According to the _____ theory, when a physiological need, such as hunger, creates an aroused tension state, it drives the organi
madreJ [45]

Answer:

the drive-reduction theory

Explanation:

The drive-reduction theory is one of the theories of motivation.

This theory contains the idea that a physiological need creates a drive, which in turn motivates an organism to satisy their need.

The theory targets homeostasis or biological balance.

When there is a need such as lack of water, the need would cause a drive to be developed (thirst).

The drive would activate a response (search for water to drink).

The response is then terminated when the need has been satisfied.
