Answer:
The energy input required for making organic compounds equals the usable energy output of respiration.
Explanation:
A reaction is endergonic (energy-consuming) process if the change in free energy is positive.
A positive change in free energy implies that energy is required to enter into the system. Let us recall that free energy is a state function. Hence, change free energy =free energy of products - free energy of reactants.
If free energy of products > free energy of reactants then the reaction is an endergonic (energy-consuming) process..
But The energy input required for making organic compounds equals the usable energy output of respiration, hence making the process spontaneous.
All the populations living and interacting within a particular geographic area make up a biological (or biotic) community. The living organisms in a community together with their nonliving or abiotic environment make up an ecosystem.
Answer:
There are different types of proteins present which are made of amino acid sub-units. Proteins play various important functions in an organism's body. Some of these functions are:
- Growth and maintenance of cells and individuals.
- Antibodies are proteins which provide immunity.
- Enzymes are proteins which catalyze different reactions.
- Many proteins allow movement of substances inside and outside of the cell membrane. They are known as carrier proteins.
- Many proteins serve as structural proteins.
Gas exchange in humans is the delivery of oxygen lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs.
The part of the amino acid that gives the molecule its unique or characteristic chemical properties would be the R-group. Every amino acid has three main groups in it namely the amino group, carboxyl group and the R group. "R" represents different organic chain that is specific to a certain amino acid which gives different properties of the molecule.
