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.

Which of the following best describes cell communication processes that are present in bacteria, yeast, and multicellular organi
Savatey [412]

Answer:

They release chemical messengers to communicate with cells they may or may not be in direct contact with.

Explanation:

Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
