You are asked to study a new inhibitor of oxidative phosphorylation. When it is added to a suspension of mitochondria carrying o

ut this process, both ATP synthesis and oxygen consumption are inhibited. You suspect that the inhibitor blocks either the F-type ATPase or the electron transport chain. You can perform an experiment that measures the consumption of oxygen and the synthesis of ATP by isolated mitochondria. In one paragraph (6 sentences maximum), explain how the uncoupler, dinitrophenol, can be used to determine whether the inhibitor blocks the ATPase or the electron transport chain.
This was all the information that was given.

Answer:

DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)

Explanation:

2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.

Which of the following types of selection tends to maintain the diversity of alleles in a population with respect to a given gen
Charra [1.4K]

Answer:

C.) Disruptive selection

Explanation:

Disruptive selection is also called as diversifying selection. Here, two or more  extreme phenotypes are preferred over the intermediate phenotype. Since more than one phenotype is preferred here, the genetic diversity of the population increases over generations.

For example, in lobsters alpha males are able to successfully mate by using force. Smaller males can also sneak in alpha males's territory and successfully mate. Hence, both alpha males and small males will be preferred over medium sized males in lobsters increasing the overall genetic diversity of population.

_______ fungi are those species that occur as either molds or yeast, depending on environmental conditions such as temperature a
Tasya [4]

Dimorphic fungi are those species that occur as either molds or yeast, depending on environmental conditions such as temperature and nutrient availability.

Dimorphic fungi are fungi that can exist in the form of both mold and yeast. This is usually brought about by change in temperature and the fungi are also described as thermally dimorphic fungi. An example is Talaromyces marneffei, a human pathogen that grows as a mold at room temperature, and as a yeast at human body temperature.

The term dimorphic is commonly used for fungi that can grow both as yeast and filamentous cells, however many of these dimorphic fungi actually can grow in more than these two forms. Dimorphic is thus often used as a general reference for fungi being able to switch between yeast and filamentous cells, but not necessary limiting more shapes.

Some diseases caused by this fungi are:

  • sporotrichosis
  • blastomycosis
  • histoplasmosis
  • coccidioidomycosis
  • paracoccidioidomycosis
  • talaromycosis
  • candidiasis

Several species of dimorphic fungi are important pathogens of humans and other animals which  includes :

  • Coccidioides immitis
  • Paracoccidioides brasiliensis
  • Candida albicans
  • Blastomyces dermatitidis
  • Histoplasma capsulatum
  • Sporothrix schenckii

Which of the following is true about ecology?
choli [55]

Answer:

The third choice would be your best answer.

Explanation:

<em>Ecology</em> is a branch of biology that<em> focuses on the relationships of organisms </em>and physical surroundings in nature.

<em>-ology</em> means the study of something

A, B, and D does not mention "studying", therefore they are incorrect.

I hope this helps.
