Answer:

The effects of tobacco smoke on the respiratory system include: irritation of the trachea (windpipe) and larynx (voice box) reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages.

Over time, the toxins from inhaled cigarette smoke break the thin walls of alveoli, leaving larger, less efficient air sacs. The sacs also begin to lose their bounce, making it harder to bring in the oxygen and expel carbon dioxide. 3 Both can become partially trapped in the lungs.

dexar [7]

Answer:

The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions

Explanation:

The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.

The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in  shape there would be no life existed.

Thus, the correct answer would be - C)

Including the conversion of pyruvate to acetyl coA, how many NADH, FADH2, ATP, and GTP molecules are produced during the kreb’s
Mnenie [13.5K]

Similar to the conversion of pyruvate to acetyl-CoA, each pyruvate molecule loses a carbon atom with the release of carbon dioxide. During the decomposition of pyruvate, electrons move to NAD + to produce NADH. It is used by cells to produce ATP.

  • NADH: Three molecules are produced in the Kleb circuit

  • FADH2: One molecule is produced in the Kleb circuit

  • ATP or GTP: From each molecule of pyruvate during the conversion of succinyl-CoA to succinic acid Two molecules of ATP are produced. The presence of the enzyme succinyl-CoA synthetase.

If a hemoglobin molecule comes into close contact with a respiring cell, the presence of CO2 in the environment will cause hemog
lapo4ka [179]

Answer:

No, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 binds to hemoglobin and the affinity for O2 decreases, causing it to release.

Explanation:

The O2 molecule is reversibly combined with the heme portion of the hemoglobin. When the partial pressure of O2 is high, as in the case of pulmonary capillaries, for example, the binding of O2 to hemoglobin and the release of carbon dioxide are favored, this is known as the Haldane effect. If, on the contrary, when the concentration of carbon dioxide is high, such as in peripheral tissues, CO2 is bound to hemoglobin and the affinity for O2 decreases, causing it to release, this is known as the effect Bohr.
