The sodium-potassium pump in animal cells requires cytoplasmic ATP to pump ions across the plasma membrane. When the proteins of the pump are first synthesized in the rough ER, what side of the ER membrane will the ATP binding site be on?

Answers

Answer 1
Answer:

Answer:

It will be on the cytoplasmic side of the endoplasmic reticulum

Explanation:

The inner mitochondria protein called  Adenine Nucleotide Translocator or ADP/ATP carrier protein, maintains  the transport of  ADP into the matrix of the mitochondria  from the cytoplasm for ADP to be available for  ATPase synthesis of ATP, from ADP and Pi(inorganic phosphate ion) during  chemiosmosis of oxidative phosphorylation in the mitochondria.

The same carrier proetin also convey  the synthesized  ATPs  back to  the Cytoplasm for cellular utilization.

Therefore the ATP binding site should at the cytoplasmic side of the E.R, because  the cytoplasm of the E.R is the site of deposits of synthesized ATP s, thus proximity of the  ATP-binding site to it is needed.

Which organism obtains its energy from dead or decaying matter?

Answers

Answer:

saprotrophs or saprophyte

Explanation:

A saprophyte or saprotroph is an organism which gets its energy from dead and decaying organic matter. This may be decaying pieces of plants or animals. They are consumers in the food chain.Bacteria and fungi are important saprotrophs.

Answer: Saprophyte is the organism obtains its energy from dead or decaying matter

Explanation: Saprophytes don't have chlorophyll and therefore, cannot prepare their food. They obtain nutrients from dead and decaying matter. Digestive juices secrete by the saprophyte on dead and decaying matter and convert it into a solution. They then absorb the nutrients from it. These enzymes convert organic food substance into a simple one.

B. Mammals use a closed, single-loop circulatory system aided by a four-chambered heart.
C. Mammals use an open, double-loop circulatory system aided by a four-chambered heart.
D. Mammals use a closed, single-loop circulatory system aided by a three-chambered heart.

Answers

A. Mammals use a closed, double-loop circulatory system aided by a four-chambered hearts.

The four chambered heart of a mammal is divided into two atria and two ventricles. Double-loop circulatory system is used. One loop for oxygenated blood, the other loop for deoxygenated blood.

Answers

It is common knowledge thathumans needed food to survive. And these foods must contain nutrents that areneeded in the body. These nutrients function in different ways that helps thehuman body function properly. The human body is made up of 65 – 90 weight % ofwater. And so, it has 65% oxygen followed by 18% carbon, 10% hydrogen, 3% nitrogen,1.5% calcium and 1.0%phosphorus. These are the major element in the human body.It does not contain fluorine.

Answer:

Hi! The four most common elements in the human body are oxygen, nitrogen,  carbon and hydrogen. Of course, the body contains trace amounts of other elements as well. :)

Most metamorphic processes take placeA. several hundred kilometers below Earth’s surface.
B. a few kilometers below Earth’s surface.
C. just below Earth’s surface.
D. on Earth’s surfac

Answers

Most metamorphic processes take place B. a few kilometers below Earth’s surface.

Further explanation

Metamorphism is the change of minerals or geologic texture in pre-existing rocks without the protolith melting into liquid magma. Metamorphism often occurs on two scales: contact and regional. Contact metamorphism occurs  locally in areas adjacent to igneous intrusions or in areas that are in contact with hot water known as hydrothermal fluids. Whereas regional metamorphism occurs over much larger areas such as rising mountain ranges, large igneous intrusions can form and warp overlying strata increasing the pressures above the intrusion. Regional metamorphism usually produces foliated rocks such as gneiss and schist.

There are other ways that metamorphic rocks can form,  Dynamic metamorphism. Dynamic Metamorphism also occurs because of mountain-building. The huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared.

Metamorphic rocks form when increased heat and pressure force physical changes in the crystalline structure of an existing rock. Under the right conditions, any type of rock can become a metamorphic rock including igneous rocks, sedimentary rocks, and even other metamorphic rocks. Therefore metamorphic processes result due to intense heat and high pressure below the Earth's surface.

Most metamorphic process takes place a few kilometres below Earth’s surface. The metamorphic process occurs due to the presence of intense heat and high pressure below the surface of Earth.

Further Explanation:

The metamorphism of rocks is due to either due to the physical or chemical alteration by dense heat and high pressure exhibited by a sedimentary or igneous material into a denser form. Rocks are compacted into a smaller volume of space due to actions of tectonic plates, presence of shearing forces for a more extended period, stress and compression. All these factors play an essential role in the wrapping and deformation of rocks.

Due to this, the metamorphic rocks are denser than the original sedimentary material. So such rocks are less susceptible to breakdown due to erosion. The process of metamorphism is also influenced by chemically active fluids that are circulated around the newly forming rock and also introduce different ions results in the formation of a new and different mineral.

Before the Ordovician-Silurian extinction, the diversity of life on Earth was growing enormously due to _____.shallow, warm, continental seas
cold, glaciated oceans
unknown reasons
comets hitting the earth

Answers

The answer is shallow, warm, continental seas.

The Ordovician-Silurian extinction happened about 450-430 million years ago. Before the extinction, most multicellular organisms lived in the seas. It was a rich life in shallow, warm, and continental seas. The climate was favorable. Reef-forming corals, as well as the first true vertebrates, some fish, appeared. Trilobites and mollusks were diverse and rich. Green algae were common in the seas.
