Basile [38]3 years ago

To maintain a line of pure-breeding peas, selective breeders would use a technique called artificial cross-pollination. This is a technique were breeders transfer pollen from the anthers of one pea plant (male parent) to a stigma of a flower (female parent).

This technique was developed by Gregor Mendel, the founder of the science of genetics. He was a monk who dedicated his time in research about how genes of plants are carried over through specific species. In his controlled experiment he used the pea plant because they are cheap and readily available from merchants who sold them in different classifications. He also used pea plants because they have the capacity to self-pollinate or cross-pollinate.

2. Explain how physical and
Anestetic [448]

Ecological models ( physical and computer) enables the Simulation of a large scale ecology which makes it easier to identify an ecological problem and also design a solution in relation to the problem identified.

An ecological model is the simulation of the ecosystem which is used for  survey, in order to identify, ecological problems, reveal the properties of the ecology, and also for the testing of scientific hypothesis. which would have been difficult to be carried out on a real ecosystem.

Ecological models can be grouped into; biodemographic, bioenergetic, and biogeochemical. and they are applicable in wildlife conservation and agriculture.

Hence physical and computer ecological models can be used to design a solution for an ecological problem by the simulation of a large scale ecology to identify and design a solution

Besides having different chemical structures, what is the difference between glucose and ATP?
AVprozaik [17]

Glucose and ATP are organic compounds composed of carbon, hydrogen and oxygen. Other than these three elements, ATP contains Phosphorus and Nitrogen. Cellular respiration breaks down glucose into water and carbon dioxide producing 38 net ATP molecules. ATP is the energy containing nucleotide in cells while the energy found in glucose is used to make ATP. The key difference between glucose and ATP is the composition of these two molecules.







What is Glucose?

Glucose is a simple sugar which is widely used in living organisms. The chemical formula of glucose is C6H12O6. It is a monosaccharide which functions as a precursor for many carbohydrates found in the organisms. In plants, glucose is produced by photosynthesis and used as a substrate for energy production. In animals, glucose is a prime energy source. In prokaryotes, glucose subjects to either aerobic respiration, anaerobic respiration, or fermentation and converts into energy molecules. Therefore, glucose can be considered as one of a primary energy source of living organisms.

Glucose is broken down completely to water and carbon dioxide by aerobic respiration. It starts with electrolysis and going via Krebs cycle and electron transport chain. In the end, it converts the energy in the nutrient glucose into 38 ATP and other two waste products. Anaerobic respiration produces less number of ATP from a glucose molecule since glucose is undergoing incomplete combustion. Some microorganisms ferment lactose to lactic acid or alcohol produce energy under anorexic conditions. All these processes use glucose as the starting substrate for ATP production.






 

What is ATP?

Adenosine triphosphate (ATP) is the energy currency in living cells. It is a nucleotide composed of three major components; namely, ribose sugar, triphosphate group, and adenine base. ATP molecules bear high energy within the molecules. Upon an energy request for growth and metabolism, the ATP hydrolyses and releases its energy for cellular needs. Three phosphate groups are responsible for the function of the ATP molecule because the energy is stored in ATP molecule inside the phospho-anhydride bonds between phosphate groups. The most commonly hydrolyzing phosphate group of the ATP molecule is the farthest phosphate group (Gamma-phosphate) from the ribose sugar.

ATP molecule bears high energy within it. Therefore, it is an unstable molecule. Hydrolysis of ATP is always feasible via an ergonomic reaction. The terminal phosphate group removes from the ATP molecule and converts into Adenine phosphate (ADP) when the water is present. This conversion releases 30.6 kJ/mol energy to the cells. ADP converts back into ATP immediately inside the mitochondria by ATP synthase during the cellular respiration.
