How many calories are equivalent to 1 pound of body fat?
aksik [14]
<span>Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical diet each day, you'd lose about 1 pound a week (500 calories x 7 days = 3,500 calories).

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  • Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.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.
