The enzyme that harnesses the energy of h+ diffusion down its concentration gradient within a mitochondrion to make high-energy

amm1812

The enzyme is: ATP synthase.

ATP synthase is an enzymatic protein complex found in the mitochondrial ridges, the thylakoid membrane, and the plasma membrane of bacteria and archaea. The role of this membrane protein is to synthesize adenosine triphosphate (ATP) from the proton electrochemical gradient of protons maintained by the respiratory chain and adenosine diphosphate (ADP), as well as inorganic phosphate, according to the following reaction:ADP + Pi → ATP.
The synthesis of ATP is based on energy conversion, via conformational changes of the subunits.A proton gradient on either side of the membrane into which the ATP synthases are inserted is necessary for their operation, which implies that the synthesis of ATP can not be done independently of a membrane. Within the mitochondrial inner membrane, it is the respiratory chain that provides the pH gradient by injecting protons into the intermembrane space during the transfer of electrons from one complex to another.

What is affected by the electrical signal sent by the fourth structure of the reflex arc?(This will be the fifth structure in th

Stells [14]

Answer:

The effector organ is affected by the fourth structure of the reflex arc.

Explanation:

When talking about the reflex arc, we refer to the sequence of events that occur for the body to react to an external stimulus.

In general terms, the peripheric nervous system receives information from a stimulus coming from the external environment. This information is sent to the central nervous system, where it is processed. From the CNS, another signal is sent as a response to the stimulus. This mechanism is known as the reflex arc.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

There are three types of neurons involved in the mechanism:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Action:

Ascending branch

The stimulus reaches the body and is received by the specialized sensory receptors. Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy. Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.

Descending branch

Once the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response. Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.

Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.

Igoryamba

Not all inspired air reaches the alveoli; 150 ml is stopped in the airway leading to the alveoli. This is called dead air space.

Alveoli are the tiny air sacs present all over the lungs. These are supposed to increase the surface area of the lungs so as to increase the amount of inhaled air. The exchange of oxygen and carbon dioxide takes place through these alveoli.

Dead air space is the unventilated area where air circulation does not take place. This air is supposed to be get trapped somewhere in the respiratory pathway or it reaches an alveoli that is poorly perfused. The dead air space can be of two types: anatomical dead space and physiologic dead space.
