What role does muscular tissue play in the digestive system?

daser333 [38]

About half of a body’s weight is muscle. Muscle tissue is of three distinct types: skeletal, cardiac, and smooth. Each type has a unique structure and a specific role. Skeletal muscle moves bones. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that changes shape to facilitate bodily functions of intestine and bladder. Here are more details about the structure and function of each type of muscle tissue in the human muscular system.

Choose all the true statements about the oxidative phosphorylation g

DiKsa [7]

Answer:

Oxidative Phosphorylation

The mitochondria is one of the double membrane organelles with specialized energy-producing functions, that is, reduced nucleotides to finally form the cellular energy currency that is ATP. The 5'-triphosphate adenosine molecule (ATP) is synthesized in the inner mitochondrial membrane as a subsequent step to the electron transport chain through oxidative phosphorylation. This process takes advantage of the flow of protons or proton motive force, detected by an electrochemical differential of H +, to produce ATP through the complex V of the mitochondrial inner membrane. Together with photosynthesis, it is one of the most important energy transduction processes in the biosphere.

Oxidative phosphorylation: Synthesis of ATP

The mitochondria, in its inner membrane, is the place of the electron transport chain and oxidative phosphorylation, | Mitochondrial electronic transport and oxidative phosphorylation are the mechanisms that aerobic organisms use to synthesize ATP from reduced organic molecules.

When does mRNA editing take place?

Ne4ueva [31]

Answer:

After transcription, some RNA molecules are altered to contain bases not encoded in the genome. Most often this involves the editing or modification of one base to another, but in some organisms can involve the insertion or deletion of a base. Such editing events alter the coding properties of mRNA.

ICE Princess25 [194]

Answer:

1. The characteristic thing about adult frog breathing is that drawing in air by lowering their mouth floor (option d).

2. The substance released by the lung secretory cells is the surfactant (option c).

3. The main divisions of the peripheral nervous system are the somatic and autonomic systems.

Explanation:

<h3>1. Breathing of the adult frog</h3>

The adult frog - while out of the water - uses a nasal breath, propelling air into its throat and oral cavity. The air content in the frog's mouth causes the internal pressure of the cavity to increase, and the floor of the mouth is modified to allow the passage of air to the lungs.

Under water, the frog's breath is cutaneous, that is, through its skin.

Adult frogs do not have gills or respiratory muscles.

<h3 /><h3>2. Pulmonary surfactant </h3>

Pulmonary surfactant is a substance produced and secreted by the pulmonary epithelium, specifically by type II pneumonocytes. The function of the surfactant is to keep the pulmonary alveoli open to allow gas exchange.

The surfactant is a substance of a lipidic and proteic nature that helps reduce the surface tension of the water, which in the socket prevents closure when the air is exhaled.

Another function is to prevent the germs - viruses and bacteria - present in the air from passing from the alveolus to the bloodstream.

<h3 /><h3>3. Divisions of the peripheral nervous system</h3>

The peripheral nervous system is dependent on the central nervous system and is made up of all the nerves that go to each of the tissues and organs of the body. It is divided into somatic and autonomic nervous systems.

Somatic nervous system is composed of nerves that drive nerve impulses to skeletal muscles, being predominantly voluntary. The involuntary response in this system is due to the existence of reflex arcs, whose center of integration is the spinal cord.
Autonomic nervous system is responsible for the innervation of coughs the internal organs, allowing their function under the coordination of the central nervous system. It is an involuntary system and is subdivided into sympathetic and parasympathetic systems.

The integration of both systems, somatic and autonomic, allows a body to perform all its functions, including the function of relationship, alertness and maintenance of organic homeostasis.
