Active Transport involves the movement of molecules such as solutes from a region of lower concentration to a region of higher concentration against concentration gradient using ATP. The transport of solutes across membrane is mediated by carriers called pumps. All the groups of ATP powered pumps contain one or more binding sites for the ATP, which are present on the cytosolic face of the membrane. Uptake of minerals or ions into the root hair cells of the plants from the soil is an example of active transport.

How many atp molecules are added to get glycolysis started

romanna [79]

Answer:

2 ATP

Explanation:

2 ATP is required to get the glycolysis started. The glycolysis process is divided into two parts, the first part is called the preparatory phase in which energy is required and the second part is called the payoff phase in which energy is produced.

During the first phase in the first step during the conversion of glucose to glucose six phosphate one ATP is consumed and in the third step during the conversion of fructose 6 phosphate to fructose 1,6 biphosphate one more ATP is consumed and in the second phase, 4 ATP is produced.

Therefore the net gain is 2 ATP because 2 ATP are added to get glycolysis started.

If ATP breakdown (hydrolysis) is inhibited, which of the following types of movement across cell membranes is also inhibited?

Len [333]

Answer:

d) passage of a solute against its concentration gradient

Explanation:

When a solute is transported against its concentration gradient, the cells use metabolic energy. To move a substance from the region of its lower concentration to that of its higher concentration, the energy of ATP hydrolysis is utilized. These types of transport mechanisms are called active transports. If ATP hydrolysis is inhibited in a cell, it would not be able to perform the uphill movement of solutes due to the lack of any source of energy to drive the process.

imagine a cell-surface receptor protein is being newly synthesized. How can it get into the membrane that it will ultimately be

motikmotik

Answer:

the steps for a new receptor synthesis:

Explanation:

Do not forget the steps vary from an eukarityc cell to prokarityc one.

IN AN EUKARYOTIC CELL:

1- Transcription: in the nucleus, mRNA is synthesized from the DNA sequence that codifies the protein. Exons are spliced if needed by spliceosomes.

2- From nucleus into cytoplasm: mRNA goes through nuclear membrane into the cytoplasm were ribosomes, substrates for protein synthesis and other organelles are.

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- (The mRNA has a signal that is recognized by the rough endoplasmic reticulum) The peptide goes into this reticulum (RER) and then into Golgi apparatus. (more chemical modifications are made if needed). By this moment the protein has an inserted portion in a lipid membrane.

6- The protein is transported in a vessel that finally fusions with cytoplasmic membrane and the receptor is in destiny. Hydrophobic aminoacid sequences are inserted in membrane.

IN A PROKARYTIC CELL:

1- Transcription (no splicing is needed, there are not exons)

2- There are not nucleus and cytoplasm divided (no transport)

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- The mRNA has a signal that is guides the growing protein to cellular membrane. Hydrophobic aminoacid sequences are inserted in membrane.

Enzymes are used in moving sections of DNA that code for insulin from the pancreas cells of humans into a certain type of bacter

victus00 [196]

Answer:

Human insulin

Explanation:

The process where by region of a DNA that codes for a particular function is transferred between organisms into cells Is described as gene transfer. This process can be used to enhance the mechanism of producing a gene that is not originally present in such organisms before. Therefore if the gene that code for insulin is inserted into a bacterial vector , the offspring of such bacteria will be able to synthesize insulin in their cell
