Which of these substances does not protect against invaders in the nonspecific immune response

Biology

B: Antigens

Explanation: Antigens itself are the invaders that causes an infection or a disease in living organism. They do not protect against invaders in non-specific response as they themselves are the ones who are invading the body.

Digestive enzymes are the enzymes that act on a particular substrate for its action at a particular PH.  

Stomach acid is the hydrochloric acid that keeps the PH of the stomach low and prevents the growth of unwanted pathogens.

Lysosomes have digestive enzymes in it. It performs the process of phagocytosis.

Open Ended Identify factors that can influence<br> enzyme activity. Describe the effect of each.
expeople1 [14]

<u>Temperature, pH, enzyme concentration, substrate concentration, and the existence of any inhibitors or activators</u> are a few of the variables that influence enzyme activity.

  • The rate of the reaction increases proportionally as the enzyme concentration rises. When diagnosing disorders, this feature is utilized to gauge the serum enzymes' activity.
  • The enzymes are highly sensitive to heat changes because they are proteins. Unlike typical chemical processes, enzyme activity is temperature-dependent. Each enzyme has a certain temperature range where it is more active, as you have seen. The ideal temperature, which falls between 37 and 40 degrees Celsius, is at this point.
  • When there is a certain amount of enzyme present, the rate of the enzymatic reaction rises as the concentration of the substrate rises until a limiting rate is achieved, after which additional increases in the concentration of the substrate have no effect on the reaction rate.
  • The most accurate way to estimate a solution's hydrogen ion concentration (H+) is to use the potential of hydrogen (pH). Additionally, it establishes whether the liquid is basic, acidic, or neutral. In general, liquids with a pH of 7 or lower are classified as acids, whereas liquids with a pH of 7 or higher are classified as bases or alkalines.
  • For optimal activity, several enzymes need specific inorganic metallic cations, such as Mg2+, Mn2+, Zn2+, Ca2+, Co2+, Cu2+, Na+, and K+. Anions are also occasionally required for enzymes.

What is the purpose of mitosis?
laiz [17]

Answer:

Mitosis is the process of cell division in which one cell gives rise to two genetically identical daughter cells, resulting in cell duplication and reproduction. The number of chromosomes is preserved in both the daughter cells.

Why is it essential for SARS-CoV2 RNA be translated on ribosomes before it can be replicated?
Natalka [10]

The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.
