The typical state of a neuron is the _____ potential, but when electrical signals stimulate it to its threshold, the _____ is im
Fudgin [204]

<u>Answer:</u>

The typical state of a neuron is the<u> resting potential</u>, but when electrical signals stimulate it to its threshold, the <u>action potential</u> is immediately observed.

<u>Explanation:</u>

The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.

Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.

C6H12O6 + O2 → 6 CO2 + 6 H2O ΔG = –686 kcal/mol. This reaction represents cellular respiration. What happens to the energy relea
Sever21 [200]
The energy released from glucose during this reaction is used and also wasted. Some of the energy is used as work while some amounts are used in other processes or stored for transfer to other organisms. Also, some of the energy is wasted in the form of heat.

after a power stroke, the myosin head must detach from acting before another powerstroke can occur. what causes
kompoz [17]

The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.

The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.

Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.

Plot blood pressure against time for one cardiac cycle in humans, drawing separate lines for the pressure in the aorta, the left
galben [10]

The expansion of the aorta causes a rise in blood volume and blood pressure.

<h3>What is the cardiac cycle?</h3>

Heartbeat pattern The cardiac cycle includes all of the physiological processes connected to a single pulse, including the electrical, muscular (pressures and volumes), sensory, and other activities. During each cardiac cycle, both ventricles and atria beat alternately.

<h3>Briefing:</h3>

The human heart's cardiac cycle includes two phases: ventricular relaxation and atrial contraction. The right ventricle has low pressure when the right ventricular systolic pressure is frequently less than 30 mm Hg. The left ventricle has a thicker wall and more muscle mass than the right ventricle as a result of the blood flowing at a high pressure. The expansion of the aorta causes a rise in blood volume and blood pressure.
