Energy requiring reactions can occur in biological systems because enzymes allow their coupling to other reactions<u> with products of lower free energy than the reactants</u>

Explanation:

Reactions which release energy are exergonic reactions and those that require energy are endergonic reactions. Exergonic reactions are with negative ∆G where the free energy (ability to do a work) of the products is lesser than the free energy of the reactants of the reaction.  

To utilize the energy that is released during exergonic reactions, endergonic reactions couple with exergonic reactions in biological systems.

Exergonic reactions are spontaneous and can be coupled with endergonic reactions because their equilibrium constant remains greater than 1.

Based on the diagram below, which part of an atom has the greatest mass?
Juli2301 [7.4K]
The nucleus will have the greatest mass. Among the 3 kinds of subatomic particles, electrons are the lightest (by several orders of magnitude), protons and neutrons are much closer is magnitude, though neutrons are slightly heavier. However, in the diagram, the nucleus contains both the neutrons and the protons, so its combined mass would be heavier than either the neutrons alone or the protons alone.

The words for the descriptions are food chain, trophic level, energy pyramid, high diversity, low diversity, etc. respectively.

<h3>Ecology</h3>
  • The feeding relationship that exists among organisms is termed the food chain.

  • Each step in the transfer of energy and matter in a community is termed the trophic level.

  • A community or group of living organisms that live in and interact with each other in a specific environment is termed an ecosystem.

  • A diagram that compares the energy used by producers, primary consumers, and other trophic levels is known as the energy pyramid.

  • An ecosystem with a high number of species is said to be of high diversity.

  • An ecosystem with a few prominent species and a low number of other species is said to be of low diversity.

  • Organisms that feed on and break down organic matter are said to be decomposers.

  • Organisms that can make their own food in the ecosystem are termed, producers.

  • Animals that feed on flesh are called carnivores.

  • A system of interlocking and interdependent food chains is called a food web.
