Biology
1 answer:
docker41 [41]3 years ago
6 0
The cross bridge cycle starts when myosin attaches to actin in a muscle cell. The process involves the initial loading of myosin with potential energy, allowing it to bind to actin. Once myosin binds, potential energy is released and the myosin's head shape changes, causing the filament to be pulled to the sacromere. This is known as the working stroke in muscular contraction.

zavuch27 [327]

Antibodies  bind to specific antigens on pathogens causing them to clump together.

When antibodies bind to antigens and cause pathogens to clump together this is called?

Agglutination reaction

It acts on antigen-antibody reaction in which the antibodies cross-link particulate antigens resulting in the visible clumping of the particle. There are two types, namely active and passive agglutination

What is antibody agglutination?

Agglutination is the process that occurs if an antigen is mixed with its corresponding antibody called isoagglutinin. This term is commonly used in blood grouping. This occurs in biology in two main examples: The clumping of cells such as bacteria or red blood cells in the presence of an antibody or complement.  

What are binding antibodies?

Neutralizing antibodies can be confused with binding antibodies, which are responsible for binding to a pathogen and alerting the immune system to its presence so white blood cells can be sent to destroy it
