Muscle contraction is an example of which of the following types of work? Group of answer choices electrical concentration heat
Citrus2011 [14]

Answer:

Muscle contraction is an example of mechanical contraction.

Explanation:

Muscular contraction is the activation of generating tension which appear in the muscle fiber as it does't change the length of muscle and is followed by muscular relaxation.

Muscle contraction is based on force and length.

The process of skeletal muscle contraction is an energy requiring process.

In order to perform mechanical work,actin and myosin  utilizes the chemical energy into ATP that ultimately require during muscle contraction and relaxation.

In a working muscle,glucose is released  from glycogen that are stored in the muscle by the process of glycolysis in which glucose broken down into ATP that is required by cells and tissues.

3. How does fluoroquinolone affect bacterial cells but not eukaryotic cells?
Valentin [98]

Answer:

In order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples.

Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.
