Latrotoxin, produced by the poisonous black widow spider, increases the release of acetylcholine. how do muscle cells respond?

1 answer:

4 0

Latrotoxin produced by widow spider affects muscle nerve endings. This toxin forms pores on the membrane of the cell. As a consequence, an influx of Ca+ ions occurs and bursts of the neurotransmitter acetylcholine (Ach) are released. Ach induces an increase in neuromuscular activity that leads to painful skeletal muscle spasms and later even paralysis.

For energy, a plant breaks apart some of the small sugars it builds. What does the plant do with the rest of its small sugars?

balandron [24]

Answer:

The plant stores them as starch

Explanation:

A typical plant synthesizes sugars from photosynthesis by using water and carbon dioxide.

$6CO_2 + 6H_20 + energy --> C_6H_1_2O_6 + 6O_2$

Parts of the sugar synthesized via photosynthesis is used to generate energy during respiration. The energy generated is useful for other metabolic processes in the plant's body.

$C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_20 + energy$

The remaining sugar is utilized in the synthesis of starch and stored in the various tissues of the plant.
