Answer

The ATP molecule is necessary in this type of transport due to the particles are moving against the concentration gradient.

Explanation:

ATP is needed for many functions that require energy, and one of them is active transport across the cell membrane.

Unlike passive transport, where particles move along the concentration gradient, active transport -which uses the energy of ATP- is characterized by mobilizing particles against the concentration gradient.

The cell membrane is semi-permeable, so some substances cannot pass freely, requiring transporters to be able to pass through it.

Other options are not true for:

<em>     A. A charged particle can move through a channel specific to it. </em>

<em>     C. There is no particle entrapment in the plasma membrane. </em>

<em>     D. Particles do not move in favor of a concentration gradient.</em>

Fill in the below mention blanks with immunity. Immunity types may be used more than once, but each sentence has only one correc
sp2606 [1]

Answer:

to. 1. Cell-mediated immunity Cytotoxic T lymphocytes attack and destroy foreign cells and viruses Antibody-mediated immunity

b.1. Cell-mediated immunity T cells mature in the thymus before they circulate. Immune.

C. 1. Cell-mediated immunity B cells differentiate into plasma cells.

re. 2. Antibody-mediated immunity Antibodies adhere to specific targets.

me. 1. Cell-mediated immunity B cells mature in the red bone marrow before they circulate the antigen.

f.1. Cell-mediated immunity Memory T cells are subsequently activated by the same 6 antigens.

g.3. Immune surveillance NK cells monitor peripheral tissues for cancer and abnormal cells.

Explanation:

Cellular immunity is mediated by the cells of the immune defense, it presents different times, in the first time the PMN appear, in the second time the antigen presenting cells, and lastly the lymphocyte lineage.

Antigen presenting cells have the ability to phagocytose and express antigen on their surface to facilitate the formation of antibodies.

Surveillance immunity refers to the lymphocytes that are responsible for monitoring or controlling cell mutations or uncontrolled growth due to genetic mutations.

Neoplastic cells express histocompatibility complexes on their surface that make them recognized by these lymphocytes and this is how they are responsible for inducing self-destruction or phagocytosis of the neoplastic cell.

Humoral immunity refers to the chemical substances that function as mediators of cell activity, these are: pro and anti-inflammatory cytokines, complement chain, nitric and nitrous acid, oxygen free radicals, interleukins, growth factors and tumor necrotic factor alpha - beta
