Why do organisms undergo fermentation in the absence of oxygen?

Biology
1 answer:
serg [7]3 years ago
5 0
 this can only happen if there is oxygen around, oxygen is toxic to organisms that are obligate anaerobes and is not required by facultative anaerobic organisms. in the absence of oxygen, one of the fermentation pathways occurs in order to regenerate NAD+; lactic acid fermentation is one of these pathways.

after a power stroke, the myosin head must detach from acting before another powerstroke can occur. what causes
kompoz [17]

The myosin head separates from actin as a result of ATP binding. The intrinsic ATPase activity of myosin then transforms ATP into ADP and Pi. The myosin head's angle is altered into a cocked state by the energy generated during ATP hydrolysis. The myosin head is now ready to move in the future.

The myosin protein is in a high-energy conformation when the head is cocked. At the end of the power stroke, the myosin head is in a low-energy position because this energy has been used up during the power stroke. ADP is released following the power stroke, but the cross-bridge is still there and actin and myosin are joined together.

Since ATP is readily available, the cross-bridge cycle can repeat, and muscular contraction can go on as long as ATP is there.

AnnyKZ [126]

Organisms that are characterized by being unicellular, photosynthetic, and having double shells made of silica are known as B. diatoms.

<h3>Photosynthetic</h3>

By converting light energy into chemical energy through a process called photosynthesis, plants and other living things can subsequently release that chemical energy to power their activities. The name "photosynthesis" comes from the Greek words "phs" for "light" and "synthesis" for "putting together." Some of this chemical energy is stored in carbohydrate molecules like sugar and starch, which are created from carbon dioxide and water. These creatures are referred to as photoautotrophs and include the majority of plants, algae, and cyanobacteria. Most of the energy required for life on Earth is produced and maintained through photosynthesis, which also produces and maintains the oxygen concentration of the atmosphere.

Organisms that are characterized by being unicellular, photosynthetic, and having double shells made of silica are known as

A. dinoflagellates.

B. diatoms.

C. kelps.

D. euglenoids.

E. foraminifera.
