What do restriction endonucleases do? what do restriction endonucleases do? they cut dna at specific sites, known as recognition
Nookie1986 [14]
Restriction endonucleases cut DNA at specific sites, known as recognition sites, to produces DNA fragments useful for cloning. Restriction enzymes or restriction endonucleases are DNA cutting enzymes found in bacteria. Each restriction enzyme recognizes one or a few restriction sites. When it finds its target sequence, it makes a double stranded cut in the DNA molecule.

One pyruvate molecule will generate _______ molecules of CO2 after completing the citric acid cycle
Rzqust [24]

Answer:

c) 3

Explanation:

Cellular respiration includes following 3 processes:

1) Glycolysis

2) Citric acid cycle or TCA or Kreb's cycle

3) Electron Transport Chain (ETC)

In glycolysis, a 3 carbon compound known as pyruvate is produced from glucose. Each glucose molecule produces 2 pyruvate molecules. Each pyruvate molecule then enters a complex known as Pyruvate dehydrogenase complex wherein the pyruvate molecule further undergoes oxidative decarboxylation to produce a 2 carbon compound known as Acetyl-CoA.

.

The Acetyl-CoA then enters citric acid cycle or TCA or Kreb's cycle wherein this Acetyl-CoA and oxaloacetate are oxidized to produce CO₂ molecules in eight steps. Each glucose molecule is capable of producing six CO₂ after the completion of citric acid cycle. Since one glucose molecule produces 2 pyruvate molecules then it means <u>a pyruvate molecule will be able to produce three CO₂.</u>

Which human body systems interact to perform temperature regulation along with the nervous and endocrine systems?
Ede4ka [16]

Answer:

Hypothalamus of human body system interact to perform temperature regulation along with nervous system and endocrine system.

Explanation:

Hypothamus is an important part of our lower brain that play a significant role in regulation of body temperature.

   Hypothalamus works with nervous system along with the other parts of our body such as blood vessels,skin and sweat gland to maintain temperature homeostasis of human body.

  When our body temperature rises at that time hypothalamus slows down the rate of metabolism of our body to restrict further increase in our body temperature and also dilates the blood vessels present beneath the skin so that body can liberate heat to the environment.

 on the other hand when the body temperature decreases at that time hypothalamus increases the metabolic rate of our body to increase the body temperature and also the constrict the blood vessels present under the skin.
