organ of the lymphatic system and of adaptive immune system that can be found
throughout the body. The major site of lymph nodes is B and T lymphocytes and

Substrate concentration affect enzyme activity -
1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached
2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.
The enzymatic reaction depends on various factors including temperature, substrate concentration, concentration enzyme, and other factors. The rate of a chemical reaction is affected by the total number of enzymes as well as the concentration of substrate
- Increasing substrate concentration increases the activity of a corresponding enzyme
- After a certain point, the rate of activity will cease to rise regardless of any further increases in substrate levels as the environment is saturated with substrate and all enzymes are bound and reacting to the maximum limit.
- A high concentration of substrate causes increases in a collision between enzyme and substrate.
- Collisions bring substrate molecules and enzymes together and increase enzymatic activity.
Thus, Substrate concentration affect enzyme activity -
1. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum rate is reached
2 Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off.

Answer:
The various steps in the transcription and translation process of protein synthesis are described below.
Explanation:
Proteins (made up of amino acids) have an important role in the various functioning process of an organism. Protein synthesis which takes place in the cells of an organism consists of two major processes: transcription (DNA to RNA) and translation (RNA to protein).
Transcription: It is the first process in protein synthesis which occurs in the cell nucleus where a single-stranded messenger RNA (mRNA) is created using a DNA strand and the genetic instructions in DNA are transferred to this mRNA. The steps in transcription are initiation, elongation, and termination. The beginning process known as initiation occurs when an enzyme RNA polymerase binds to a promoter (region of a gene) and the DNA unwinds. One of the DNA strands acts as a template and the enzyme reads the bases in the template DNA strand.
The next step is elongation, where the RNA polymerase builds a strand of mRNA by the addition of nucleotides using complementary base pairs. Here, adenine (A) in the DNA binds to uracil (U) in the RNA. Termination is the last step in which the transcription process ends when the RNA polymerase comes across a termination sequence in the gene. Thus, the completed single-stranded mRNA detaches from DNA.
Translation: It is the second process in protein synthesis which occurs in the ribosome of the cell where the genetic information in mRNA is used to create a protein from amino acids. A triplet of nucleotides is called a codon and they define amino acids. There are 64 possible codons and the codon, AUG acts as the start codon which initiates translation in addition to specifying the amino acid methionine. In the initiation step, the first amino acid in the polypeptide chain is brought by transfer RNAs (tRNAs) to bind to the start codon of mRNA. During elongation, each type of tRNAs in the cytoplasm bound to a specific codon on the mRNA template and adds the corresponding amino acid to the polypeptide chain. Stop codons (UAA, UAG, or UGA) terminate protein synthesis and release the polypeptide.
Answer:
how are we supposed to know how many we read today?
Explanation:
because not many people count how many words they have each week.
Carbon six, Hydrogen 12, Oxygen 6
