If heart rate is 60 beats per minute (bpm) and the average stroke volume is 100 mL/beat, what is the cardiac output?
6 L/minute.
The cardiac output is the amount of blood that the heart pumps per minute. To calculate it, we can multiply the heart rate (60 bpm) by the stroke volume (100 mL/beat).
So, the cardiac output would be:
60 bpm x 100 mL/beat = 6000 mL/minute or 6 L/minute
Cardiac output refers to the amount of blood pumped by the heart in a particular unit of time, typically measured in liters per minute (L/min). It is determined by the product of the heart rate (HR), which is the number of heartbeats per minute, and the stroke volume (SV), which is the volume of blood pumped from the ventricle per beat. The formula for cardiac output is CO = HR x SV [1]. It is an important measure of heart function and can be affected by various factors such as exercise, heart disease, and medications

Explain why it is important that ATP is broken down into ADP.
ATP (adenosine triphosphate) is the main source of energy for cellular processes. When ATP is broken down into ADP (adenosine diphosphate), energy is released and can be used for various cellular activities such as muscle contraction, active transport, and protein synthesis.
It is important that ATP is broken down into ADP because it allows for the continuous recycling of energy. Once ATP is used for cellular work, it becomes ADP, and can be converted back into ATP through cellular respiration. This process ensures that cells have a constant supply of energy to carry out their necessary functions. Without the breakdown of ATP into ADP, cellular processes would not have access to the energy they require, which could result in cell death or malfunction.

The central chemoreceptors in the medulla are normally most sensitive to
The central chemoreceptors in the medulla are normally most sensitive to changes in the concentration of hydrogen ions in the cerebrospinal fluid, which is primarily influenced by the levels of carbon dioxide in the blood.
The central chemoreceptors play a crucial role in maintaining the acid-base balance and regulating the respiratory system. When there is an increase in carbon dioxide levels in the blood, it leads to a higher concentration of hydrogen ions in the cerebrospinal fluid. This change is detected by the central chemoreceptors in the medulla, which then transmit signals to the respiratory control center. As a result, the respiratory rate and depth increase to facilitate the removal of excess carbon dioxide from the body, restoring the balance of pH in the blood.
Conversely, when carbon dioxide levels decrease, the concentration of hydrogen ions in the cerebrospinal fluid also reduces, leading to a decrease in the respiratory rate and depth, this ensures that carbon dioxide levels in the blood remain stable and the body's acid-base balance is maintained. In summary, the central chemoreceptors in the medulla are highly sensitive to changes in hydrogen ion concentration in the cerebrospinal fluid, which is directly related to the levels of carbon dioxide in the blood. These chemoreceptors play a vital role in regulating the respiratory system and maintaining the acid-base balance within the body. The central chemoreceptors in the medulla are normally most sensitive to changes in the concentration of hydrogen ions in the cerebrospinal fluid, which is primarily influenced by the levels of carbon dioxide in the blood.
