Answer:

B)inducible

C. )extracellular enzyme

Explanation:

Catalase is an enzyme that is engaged during the the decomposition of hydrogen peroxide to form water and oxygen, it is posses by all living organisms because of their exposure to oxygen, hence it protect the cell from oxidative damage by reactive oxygen species.

Catalase enzymes function in our liver by breaking down harmful hydrogen peroxide into oxygen and water ,during this reaction , the bubbles of oxygen gas that escape create a foam that will help to disinfect any surface touch by the raw liver during this process. Catalase enzymes are extracellular enzyme and are inducible.

The per capita ecological footprint is the total ecological footprint for a given country or area
Phantasy [73]

The per capita ecological footprint is the total ecological footprint for a given country or area is false and is therefore denoted as option B.

This is referred to as the amount of land which is required to ensure that there is adequate use and sustainability of the resources which are present in area at a given period of time.

The per capita ecological footprint is the average ecological footprint for a given country or area and not the total ecological footprint which is therefore the reason why false was chosen as the most appropriate choice.

During an infection with listeria, an intracellular bacterium, antigen presenting cells will present antigen on mhc class ______
Marat540 [252]

During infection with Listeria, an intracellular bacterium, APCs will present antigen on MHC II molecules and triggers a phagocytic property by stimulating the release of macrophages.

What is the role of macrophages in Phagosomes?

Phagosome maturation was formerly regarded to be a very simple notion that described how much phagosomes had united with lysosomes.

  • Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.
  • Proteins, such as the NADPH oxidase complex that creates the superoxide burst, may be seen being assembled on the phagocytic cup even before they are fully formed.
  • When the phagosome closes and the maturation process begins, it becomes increasingly acidic and hydrolytically active, and it transiently fuses with the recycling endosomal system, the secretory system, including secretory lysosomes, multi-vesicular bodies such as the MHC class II (MIIC) compartment, and even the endoplasmic reticulum.

Difference between Cellular and Humoral immunity?
Harrizon [31]

Cellular immunity kills pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.

<h3>What is the difference between Cellular and Humoral immunity?</h3>

The main difference between humoral and cell-mediated immunity is that humoral immunity produces antigen-specific antibodies, whereas cell-mediated immunity does not produce antigen-specific antibodies. The cellular immunity destroys pathogens and harm microbes that are present inside the cell, whereas humoral immunity kills pathogens outside the cell.

So we can conclude that cellular immunity kills pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.
