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:
it's too early for this, also im pretty sure all we know is that their ancestors are wolves and that's it.
Explanation:
I’m pretty sure that’s right
Answer:
C. Point B
Explanation:
The exposed curve represents a logistic growth model. Population growth depends on density. Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get qual to each other.
Referring to population size as N, when
- N<K, the population can still grow.
- N approximates to K, the population´s growth speed decreases.
- N=K the population reaches equilibrium,
- N>K, the population must decrease in size because there are not enough resources to maintain that size.
The sigmoid curve represents the logistic growth model.
- Point A: During this period, the population size is relatively stable. Little growth is expressed.
- Point B: At the beginning of this period, population growth increases softly. The more individuals are in the population, the more that reaches sexual maturity and get to reproduce, leaving fertile offspring. This fertile offspring also get to reproduce and leave more fertile individuals. At the end of the period, the curve shows a sharp slope, reflecting the significant increase in the population reproductive rate.
- Point C: At the beginning of this period, the population keeps on growing exponentially. But at the end of the period, the curve tends to stabilize, meaning that the population stops growing in size so fast. The population slow and gradually reaches the equilibrium point, K.
- Point D: The population got to stabilize.
