What happens when the supply of energy-rich molecules in a muscle is used up?

Biology

Rufina [12.5K]3 years ago

If there is no energy left for the muscle, then the muscle is tired and needs to rest. This is because there will be no more energy (in the form of ATP) to supply the excitation-contraction coupling mechanism (the mechanism for muscle contraction, which needs energy).

<em>In the event of this situation, the person will not be able to move the muscle with depleted energy source at all.</em>

topjm [15]

Answer:

- fibrous joint between radius and ulna: C. syndesmosis

- fibrous joint that unites bones of the skull: H. suture

- articulation between teeth and bone: J. gomphosis

- joint with a cavity between bones: E. synovial

- the epiphyseal plate: F. synchondrosis

- articulation between two pubic bones: A. symphysis

- permits opposition and reposition:  B. saddle  

- fibrocartilagenous fluid filled sacs outside the joint cavity: G. meniscus

- most common degenerative joint disease: D. osteoarthritis    

- movement of the sole laterally:  I. eversion  

Explanation:

The syndesmosis can be defined as a fibrous joint held together by ligaments. Sutures are fibrous joints of tissue that link the cranial bones of the skull. A gomphosis is a mobile fibrous that binds the teeth into sockets in the mandible and maxilla. Synovial joints are joints found between bones that move against each other (e.g., shoulder bones). They (synovial joints) are the most common class of joints found in the body. A symphysis is a cartilaginous, slightly movable, joint between two bones. A saddle is a synovial joint whose opposing surfaces are concave and convex, respectively. Osteoarthritis is the most common type of arthritis, this condition occurs when the protective cartilage surrounding the bones wears away over time. Finally, eversion refers to a type of movement of the foot which occurs in the auctioneering joint.

The entry of the sperm nucleus is facilitated by C) acrosome reaction. The acrosome is the head-like structure at the front of the sperm cell. This contains digestive enzymes that break down the outer membrane of the egg cell, allowing the nucleus of the sperm cell to enter and fuse with the nucleus of the egg cell. Hope this helps, and please give me brainliest, as I was first to start typing.
