Enzymes and a single substrate use the lock-and-key mechanism.
The "lock" is the enzyme and the "key" is the substrate

Answer:

Enzymes and Substrate

Explanation:

The lock and Key mechanism was first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme which has a definite shape, with only a keyhole which fits exactly to the right key, that its then the substrate. This mechanism is used to explain the way enzymes are specific or can only degrade a certain substrate.

Proton pumps embedded in the cell membrane use ATP to move hydrogen ions across the membrane. Which of the following best descri
DIA [1.3K]

Answer:

Explanation:

Although protons resemble other positive ions such as Na+ and K+ in their movement across membranes, in some respects they are unique. Hydrogen atoms are by far the most abundant type of atom in living organisms; they are plentiful not only in all carbon-containing biological molecules, but also in the water molecules that surround them. The protons in water are highly mobile, flickering through the hydrogen-bonded network of water molecules by rapidly dissociating from one water molecule to associate with its neighbor, Protons are thought to move across a protein pump embedded in a lipid bilayer in a similar way: they transfer from one amino acid side chain to another, following a special channel through the protein.

Mrac [35]

Answer:

The receptors in the aortic and carotid bodies are chemoreceptors.

Explanation:

Chemoreceptors are specialized cells that are responsible for detecting and converting chemical signals into biological signals, to relay that information to the brain, where they will finally be interpreted. Among them we find the peripheral chemoreceptors, which are the aortic bodies, located along the wall of the aortic arch and innervated by the vagus nerve, and the carotid bodies, located in the neck. . Carotid bodies are stimulated by variations in the concentration of oxygen and carbon dioxide in the blood, as well as variations in blood pH. When the pH decreases the CO2 increases and the oxygen decreases, they activate the chemoreceptors to increase breathing.
