Electricity is added to recharge a battery. What is added to ADP to form ATP?
White raven [17]

Electricity is added to recharge a battery. A third phosphate group  is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

The DNA segment that carries information for building one protein or polypeptide chain is called a(n) ________.
kirill115 [55]

Answer:

The correct answer is a gene

Explanation:

The DNA segment that carries information for coding one protein or polypeptide is called a gene. According to one gene-one polypeptide hypothesis, each gene is responsible for making a single chain of the polypeptide.

Originally it was said that one gene codes for one enzyme but later it was found that some gene also codes for non-enzyme proteins and single polypeptide chains. So after this research, the theory was modified and one gene-one polypeptide theory came. Therefore the right answer is gene.

Describe how the following stages occur in a neuron in terms of ion movement across the cell membrane: resting potential, thresh
adell [148]
<span>We have two surfaces of nerve cell the outer and inner surface

- resting : when the outer layer ion charges more positively than the inner layer - depolarization : we have the counter part of this state
- repolarization : return to the polarization
- hyperpolarization : the inner negative ion charges will be more negative even more than the resting potential

I hope that this is the answer that you were looking for and it has helped you.

Which molocule is used to cut out a section of dna
pshichka [43]

Answer:

Restriction enzymes (endonucleases) are used to cut the DNA into fragements.

Explanation

Restriction enzymes are obatained from bacteria where they are utilized by bacteria for protection against viruses. Restriction enzymes are used in biotechnology research. There are several restriction enzymes and each cut the DNA at specific site known as recognition site which is usually 4-8 neucleotide long. They produce sticky ends (cutting the both DNA strand on different site) and blunt ends (cutting the both DNA strand on same site) on DNA fragments.
