Answer: Exergonic reaction; Endergonic reaction
In coupled reactions, the energy released by an exergonic reaction is used to drive an endergonic reaction. ATP breakdown is often coupled to cellular reactions that require an input of energy.
Explanation:
Cellular reactions include Exergonic and endergonic reactions. An exergonic reaction is one that occurs spontaneously and brings about the release of energy (in form of ATP). On the other hand, an endergonic reaction proceeds only with the input of energy.
Thus, exergonic reactions are usually coupled to endergonic reactions
In coupled reactions, the energy from an energy-releasing exergonic reaction, like the breakdown of ATP, is used to drive an energy-requiring endergonic reaction. These reactions usually occur together in a cell.
In coupled reactions, the energy released by a exergonic reaction is used to drive an endergonic reaction. An exergonic reaction is a chemical reaction where energy is released, often in the form of ATP (Adenosine Triphosphate). On the other hand, an endergonic reaction requires energy to proceed.
In a cell, these types of reactions often happen together (or are coupled) so that the energy released by an exergonic reaction, like the breakdown of ATP, gets immediately used to power an endergonic one, such as the synthesis of cellular components or the transport of molecules across the cell membrane.

Answer:
Gene expression
Explanation:
The information a living organism needs is embedded in the genes found in the genetic material (DNA) of that organism. These information, however, are stored in the DNA and needs to be used to produce useful products (usually proteins). This process is called GENE EXPRESSION. Gene expression occurs in two steps; transcription and translation.
Transcription is the process whereby the information in the DNA is copied into a RNA molecule. It involves synthesizing a complementary strand of mRNA from a DNA template. This mRNA is then used as a template to direct the production of sequence of amino acids, which determines the protein. Transcription occurs in the nucleus of eukaryotes while it occurs in the cytoplasm of prokaryotes. Translation occurs in the cytoplasm of both prokaryotes and eukaryotes.
The speed of the frog is understood to be 1m/sec.and the velocity is that through which a frog can turn and jump in a different direction in 1 sec the distance is 1 m. This returning back to the original position represents no displacement.
Displacement may be defined as the rate of change in the position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position.
Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s).
Speed may be defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. It is a scalar quantity as it has only direction and no magnitude.

Answer:
The speed of the frog is 1m per second the velocity is he can turn and jump in a different direction in 1 second the distance is 1m and there is no displacement.
