Which statement best describes the initial process of N-linked glycosylation in the endoplasmic reticulum

Answers

Answer 1

Answer:

The oligosaccharide is assembled on the lipid carrier at the membrane of the ER

Explanation:

N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.

The question is incomplete, below is the complete question.

ATP and photovoltaic cells are similar because

A. they are both key components of plant cells.

B. they both produce chemical and electrical energy.

C. they are both key components of solar panels.

D. they both use energy from the sun to separate electrons from atoms.

The correct answer to the question is option D

ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.

Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.

These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.

When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.

In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins

Answers

Answer:

Estradiol has a higher partition coefficient than H+ ions

Explanation

Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

A metal rod would not be a good choice for roasting marshmallows because
metal transfers thermal energy.

Answers

Answer:

O As the air around the campfire is heated and becomes less dense, it rises and moves upward.

Explanation:

This is true because, the convection transfer needs the particle of elements to transport the heat from where it is in abundance to where it is in less abundance. Just like a water boiling becoming hot at the point closer to the fire than the top of the pot, so also will the air around campfire transfer heated air from the place closer to the campfire to upwards aware from the fire.

Convection is the flow of air around the campfire when it is heated and the decrease in density as it rises upward in the atmosphere. Thus, the correct option is C.

What is convection of heat?

Convection is the transfer of heat from one place to the other due to the movement of fluids present in it. It is a distinct method of heat transfer in systems. The convective heat transfer involves combined processes of conduction and advection in a system and its surrounding. Convection is the dominant form of heat transfer in liquids and gases.

The thermal radiation in the fire is mostly in the form of infrared waves and visible light. However, the campfire heat transferred via convection shoots straight up in the sky and never reaches to the ground level.

Therefore, the correct option is C.

It is best in deep forests where dead organisms have not been disturbed.

Answers

Answer:

It gives useful information about environments and the ways past organisms lived

Explanation:

A fossil is basically any preserved remains or trace of any organism that once lived in the past. Bones, shells and exoskeletons are examples of fossils that can be studied through Paleontology.  

From fossil studies, we can tell how long these lives existed on earth and how varying plants and animals are related to one another. We can often find out how and the places they lived and their environments as well.  

Which correctly lists the three main ocean zones?

O open ocean, deep, continental

Answers

Answer:

Honestly I think it's C

Explanation:

The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.

What are the three main zones?

The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.

The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.

Apart from the three main ocean zones, there other oceanic zones are  epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.

Therefore, the three main ocean zones are neritic, bathyal, and abyssal.

When Toby turned eight, his father decided to start training him on the trapeze. Toby loved the trapeze. He quickly mastered swinging and transferring between trapeze bars. After only a few months of training, Toby was part of his father's act. As the years passed, Toby learned to do more stunts. The father-son trapeze act became increasingly exciting and dangerous. One evening, Toby was especially excited about his performance. He was going to execute a triple somersault in mid-air without a net below him. "You are going to be the biggest star of the circus! Here is a shiny gold suit to show the world how brilliant you are!" Toby's father said as he gave him a new costume to wear. Toby's mother however was not supportive. She cried and begged Toby and his father to use the net. "Mama, don't worry. I practiced this act a million times and never fell once!" Toby told his mother. "Toby is a master. I would not let him do the trick if I had any doubts. The crowds will love it!" Toby's father said. When it was time for the trapeze act, Toby turned to the audience and posed with his arms raised high. Then, he grabbed the first trapeze bar, and leaped from the platform. For the first few minutes, Toby did his usual tricks. "Ladies and gentleman, please give me your undivided attention! Tonight, Toby McAlister is going to perform a death-defying stunt right before your very eyes. He will attempt the triple somersault without a net!" the ringmaster announced. Then, several workers entered the ring and removed the safety net. The audience grew still and silent. Toby's mother sat in the front row and prayed that Toby would not fall. As Toby's feet left the platform, Toby's mother held her breath and closed her eyes. Suddenly, the audience gasped. Toby's mom felt her heart stop for a moment. Then, the arena erupted with applause. Toby's mom opened her eyes to see that Toby's father was holding him by the feet as he hung upside down.
