The cell respiration pathway that occurs in the mitochondria is

KengaRu [80]

Answer:

The path of cellular respiration that occurs in the mitochondria is aerobic.

Explanation:

Aerobic respiration is what uses oxygen to extract energy from glucose. It is carried out inside cells, in organelles called mitochondria, through which chemical energy is obtained from the breakdown of organic molecules.

To obtain glucose energy, a process occurs in which the carbon is oxidized and when it reaches the mitochondria it mixes with the water making a chemical compound called glucositisa ( pathway responsible for oxidizing glucose to obtain energy for the cell) in which the oxygen from the air is the oxidant used.

Aerobic respiration is a process consisting of chemical reactions that are grouped into 3 stages, taking into account the place of the cell in which each one develops.

1) Glucolisis: It is carried out in the cytoplasm.

2) Krebs Cycle: It is produced in the mitochondria matrix.

3) Respiratory Chain: Occurs in mitochondrial ridges.

A host organism needs time, often days, to mount an immune response against a new antigen, but memory cells permit a rapid respo

nikklg [1K]

Answer:

The answer is <em><u>D. </u></em>

Explanation:

Viruses can evade the processing and presentation of antigens, for example by interfering with the expression of MHC class I proteins, although this increases their susceptibility to be detected by natural killer cells (NK). However, some members of the herpesvirus, papillomavirus, retrovirus, poxvirus and flavivirus families have also developed strategies to escape the attack of NK cells and promote their survival, inhibiting cell apoptosis. Finally, some pathogens often change surface antigens frequently, as in the case of influenza viruses (orthomyxovirus).

The human immunodeficiency virus (HIV) affects CD4 + T cells and degrades the host's ability to counterattack with a strong cell-mediated immune response. There are so many tactics of immune evasion used by HIV, which have so far hindered the development of an effective vaccine.

Can you identify the class of organic molecule to which these molecular structures and examples belong? Part A Sort these items

sattari [20]

There are four classes of organic molecules that are essential to all living organisms.

1. Carbohydrates:

Components: monosaccharides. Functions: energy for cell, raw material, energy storage, and plant cell support Ex: glucose, starch, glycogen, cellulose

2. Lipids (dont form polymers): Components: glycerol, fatty acid, components of a fat molecule Functions: energy storage, cell membrane components, and hormones Ex: fats, phospholipids, and steroids

3. Proteins:

Components: amino group, carboxil group, R group, and amino acid Function: enzyme, structural protein, movement, transport, communication, defense, storage, receive signals Ex: lactose, hair, tendons, muscles, hemoglobin, signal proteins, antibodies, egg albumin, receptor protein

4. Nucleic acids:

Components: phosphate group, nitrogeneous base, ribose or deoxyribose, nucleotide Functions: heredity, DNA

Ex: code for proteins, DNA and RNA

Answer:

200g fruit

Explanation:

fruit = 500 x 40% = 500 x 40 / 100 =

= 500 x 0.4 = 50 x 4 = 200g
