Answer:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs.

Explanation:

Each gram of protein contains 4 calories. Protein makes up about 15 percent of a person's body weight. Chemically, protein is composed of amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, oxygen or sulfur.

Neurons in the ______ , control motor reflexes.
yan [13]

Neurons in the <u>spinal cord</u>, control motor reflexes, which allows rhythmic and automatic movements to be carried out.

The spinal cord represents the lowest level in the hierarchical system that regulates reflex motor activity, voluntary movements, and body posture.

Therefore, their neurons have been organized into circuits that participate in simple automatic gait movements and simple defensive movements (withdrawal of the muscle in the event of any aggression) through reflex responses.

The motor neurons of these circuits are located in the anterior horns where they are arranged forming the so-called "poles" of motor neurons, equivalent to true motor neuron nuclei.

  • Alpha motor neurons their axons are myelinated and they group together in the medulla and form columns that are known as motor nuclei.

  • Gamma (γ) motor neurons innervate muscle fibers of the muscle spindle.

  • Interneurons can be excitatory or inhibitory.

Therefore, we can conclude that neurons in the spinal cord, control motor reflexes, they present functional interactions between them and this allows rhythmic and automatic movements to be carried out with ease through reflex responses.

chegg e. coli has to be grown in the presence of to the lac operon. group of answer choices lactose: repress lactose: induce glu
zhuklara [117]
<h3 />

The lac operon of E. coli contains genes involved in lactose metabolism. It's expressed only when lactose is present and glucose is absent.

<h3>How is the lac operon triggered by E. coli?</h3>

The lac operon of E. coli contains genes related to lactose metabolism. Only when lactose and glucose levels are low does it manifest symptoms. Two regulators that control the operon's "on" and "off" states in response to lactose and glucose concentrations are lac repressor and catabolite activator protein (CAP).

<h3>Why does E. coli prefer glucose to lactose?</h3>

Because it promotes quicker development than other sugars and is the first sugar to be consumed in sugar combinations, glucose is frequently the best carbon source for E. coli.
