Amiraneli [1.4K]

Answer: CheA

Explanation:

Cytokines and chemokines are proteins that bind to other, cells that require specific antibodies to these proteins, making them a form of communication between the system cells immune. That process by which cells are sent to move through a chemical stimulus is called chemotaxis. The internal environment is responsible for the signal transduction part received by the receivers. CheR is a relatively slow enzyme and its main function is to methylate the receptors. It is divided into two domains: one responsible for substrate identification and the other for transferring methyl groups to the receptor.

does a cross bridge in a sarcomere of a fast fiber produce the same amount of forces as a cross bridge in a sarcomere of a slow
Zolol [24]

Answer:

Cross bridge in a sarcomere of a fast fiber produce higher amounts of force as compared to a cross bridge in a sarcomere of a slow fiber

Explanation:

When a muscle contracts, a cross bridge is formed between actin and myosin. The sarcomere shortens when a muscle contracts by reforming cross bridge. In general a muscle fiber is of three types – a) slow, b) Fast and c) intermediate.  

The sarcomere of fast fiber generates high force but for a short period of time. On the other hand, sarcomere of slow fiber generate lower amounts of force but this force lasts for a longer period of time. Due to this difference, fast fibers are the predominant fibers in the body
