Answer:Trypsin inhibitor blocks trypsinogen's catalytic activity.
Explanation: Trypsin are protein inhibitor that reduces trypsin activity by controlling it activation and catalytic reaction.
They binds to trypsin thereby preventing protein from binding to the trypsin and therefore inhibit digestion process. They are called anti nutritional factor because they inhibit digestion.
Trysinogen are found in the body and it prevent protein such as pancrease from been broken down. Trypsin inhibitor blocks trypsinogens activity in animal by preventing its activation in the body by binding to it active site.
Each cell contains thousands of different proteins.
Answer:
The product of glycolysis is two molecules of pyruvate. It is a three-carbon compound. This pyruvate again undergoes oxidation in the cytoplasm. This process is called pyruvate oxidation which produces Acetyl CoA. The Acetyl CoA is a two-carbon molecule.
Acetyl CoA again used for the citric acid cycle. This is also called as Kreb's cycle / TCA cycle. Because citric acid has 3 carboxylic groups. The acetyl coenzyme produces NADH, FADH2, ATP. The citric acid cycle occurs in the mitochondrial membrane. This is an 8 step process. The first product is citric acid. The other products of each step are isocitrate, alpha-ketoglutarate, succinyl CoA, succinate, Fumarate, L - malate, and Oxaloacetate (OAA).
Another process of aerobic respiration is the electron transport chain ( ETS). Here the energy stored in NADH, FADH2 in the citric acid cycle are utilized. It is a chain of electron carriers. ETS occurs in the inner membrane of mitochondria.
In short, the glucose splits by glycolysis and produces ATP, NADPH, and final product pyruvate. The pyruvate is oxidized and forms acetyle coenzyme. This is used in the TCA / citric acid cycle. In this process also NADH, FADH2 which forms electrons are produced. Theses electrons are carried by different electron carriers and accepted by oxygen.
In the process of pyruvate oxidation 6 ATP, and in Kreb's cycle 18 ATPs, in ETS, 4 ATPs are produced. In addition to this in glycolysis produces 4 ATPs. The total number of ATP in aerobic respiration is 32 ATP.
Answer:
(c) directional selection
Explanation:
Directional selection is a type of natural selection that occurs when members of a population of a species with a particular extreme phenotype is selected or favored against the other phenotypes when natural forces act on the population of a species. Individuals having the particular traits that are favored survive and become more common that others with traits that are less favored.
Directional selection may likely result in the species of butterflies in which darkly collared butterflies are not preyed upon, ensuring their survival, while the other butterflies with other colors will be phased out with time. Darkly colored butterfly will be selected for while the others will be selected against.
