I am Lyosha [343]3 years ago
6 0

Answer:

Energy is required to move the hydrogen ions across the membranebecause the hydrogen ions are movingagainst the concentration gradient. High potential energy electrons provide the energy necessary to pumphydrogen ions across the inner mitochondrial membrane.

DENIUS [597]

Answer:

forming

Explanation:

Team development is a process wherein different individuals come together and learn to work efficiently to carry out a specific task.

There are certain stages that a team goes through during the development phase and these are:

1. Forming

2. Storming

3. Norming

4. Performing

5. Adjourning

The stage of team development where the different members get to know each other and orient themselves concerning each other's space is known as forming. This is a stage where they get acquainted with each other and explore and learn the ideas fo different team members.

Since in the given situation the scientists and dentists are holding a team meeting to get acquainted with each other and formally introducing themselves, the team is currently in the development stage of forming.

How are energy inputs and outputs related to chemical reactions
GREYUIT [131]

The large number of areas covered by the chemical energetics can be explained by the different forms in which chemical energy can be released: heat and combustion work, electrical energy in electrochemistry, radiant energy in chemiluminescent systems.

The chemical energy provided by a reaction reflects the energy balance associated with the electronic modifications suffered by the species involved.

From an energy point of view, a chemical reaction between molecules can be schematized in two stages. The first requires a supply of energy and corresponds to the rupture of the bonds of the reactant molecules with release of the atoms which constitute them.

The second releases energy and concerns the creation, by recombination of these atoms, of new bonds entering the structure of the reaction molecules.

As a general rule, the energy released in the second stage is greater than the first. We are talking about exothermic reaction. The difference between these two energies (reaction enthalpy) measures the amount of chemical energy transferred to the external environment.

It is conceivable that this quantity translates, not only the number, but also the strength of the connections involved.
