Answer:

receptor down-regulation

Explanation:

Downregulation is a control mechanism by which a cell decreases the amount of a cellular component, such as RNA or protein, in response to an external variable. In contrast, a reactive increase of a cellular component is called upregulation. An example of downregulation occurs when insulin binds to its receptor and the complex is endocyted in the cell in response to hormonal signaling.

which statement correctly compares and contrast the three stages of cellluar respiration that occurs in the presence of oxygen
Lapatulllka [165]
<h2><u>Full Question:</u></h2>

Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.

<h2><u>Answer</u>:</h2>

Each stage produces ATP, but only the first stage occurs in the cytoplasm.

<h3><u>Explanation</u>:</h3>

Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.

ATP is produced from each astep of cellular respiration. So the correct option is option C.

Solar, wind, and hydroelectric energy<br> are examples of<br> resources.
strojnjashka [21]

Answer:

Renewable Energy Resources.

Explanation:

Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.

Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.

Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.
