Answer:
Lactic acid
Explanation:
Fermentation may be defined as the breakdown of glucose molecule in the limited supply of oxygen with the help of microorganisms.
Pyruvate molecules and electrons waste product combine together in fermentation to yield lactic acid and two molecules of ATP. The transfer of electron from NADH to pyruvate molecule generates the lactic acid.
Thus, the correct answer is option (D).
Answer:
Each trophic level represents the beings of an ecosystem and their amount of energy.
Explanation:
In a food chain, the highest energy level is made up of producers (e.g. chlorophyll plants), with the rest of the ecosystem dependent on their energy, captured from sunlight and stored in organic compounds.
The next trophic level belongs to primary consumers (herbivores) and then secondary consumers (carnivores).
From the producers, only part of the amount of energy is passed from one trophic level to the other, In other words, the higher the trophic level, the less energy is absorbed.
In an energy pyramid, each area is represented by a trophic level (from a food chain) of size proportional to its amount of energy.
The elements of the food chain are represented with the producers at the base (higher energy) and the consumers of each trophic level above.
As explained earlier, the amount of energy absorbed at the highest levels is low and therefore insufficient to support another trophic level.
Answer:
Avermectins
Explanation:
Avermectin is a class of drug that are used as a pesticide to kill the helminths. Averctin may exist in the form of monosaccharide as well as disachharide.
The averctin drug blocks the transmission of electrical impulse in the brain. This drug inhibits the neuromal transmission in helminths and thus proves to be a effective drug to kill the helminths.
Thus, the correct answer is option (2).
Glycogen is found in animal cells and starch is found in plant cells.
Glycogen is a polysaccharide of glucose. It is used to store energy in animal cells. The linear chains in a glycogen molecule are linked by α(1,4) glycosidic bonds while the branched chains are linked by α(1,6) glycosidic bonds. Glycogen breaks into glucose to provide energy to the body when needed.
Starch is the polysaccharide of plants and is made up of glucose units. They are joined by glycosidic bonds. It is found in most plant-based foods and is a common carbohydrate in the human diet. It has two types of molecules helical amylose and branched amylopectin. Amylose forms 20-25% of starch whereas amylopectin forms 75-80% of it.
