Ans.
In humans, there are total of 46 chromosomes in each cell that show 23 pairs of chromosome. During reproduction, meiosis occurs in germ cells that leads to formation of daughter cells or gametes that contain half of the chromosomes as present in parent cells. Thus, each gamete (either male or female) contains 23 chromosome.
During fertilization, fusion of male gamete or sperm(with 23 chromosomes) and female gamete or ovum(with 23 chromosomes) to form zygote that develops into multi-cellular offspring with 46 chromosomes.
Thus, 'a child inherit 46 chromosomes from his or her parent (23 chromosomes from each parent).'
D is not right.............
Answer:
The correct answer is a Inhibit the enzyme and slow the rates of Glycolysis and citric acid cycle.
Explanation:
ATP accumulation result in blocking the activity of the rate limiting enzyme of glycolysis Phosphofructokinase that catalyses the conversion of fructose-6-phosphate to fructose -1,6-bisphosphate .
ATP is an Allosteric inhibitor of Phosphofructokinase enzyme and this enzymatic inhibition decreases the rate of glycolysis and as the rate of glycolysis decreases the rate of TCA cycle is also decreased because TCA cycle depends on glycolytic end product Pyruvate. As glycolysis rate is decreased pyruvate is not formed in a sufficient amount to carry out its conversion to Acetyl CoA and enters into TCA Cycle.
Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .
Most of the mass of an atom is concentrated at the center of the nucleus.
Atoms are made up of three subatomic particles called
1. Protons
2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
