Ksenya-84 [330]3 years ago
3 0

Answer:

0 %

Explanation:

The relative activity of trypsin has decreased to zero by pH 11.

It will still be zero at pH 14.

The percentage of maximum activity will be 0 %.

Name the things which help in the preparation of carbohydrates in plants​
Salsk061 [2.6K]

Answer:

People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.

The prolonged electrical depolarization of cardiac muscle cells that occurs during contraction is due primarily to the persisten
luda_lava [24]

Answer:

The prolonged electrical depolarization of cardiac muscle cells -that occurs during contraction- is due primarily to the persistent influx of calcium ion

Explanation:

The action potential of the heart muscle is longer with respect to skeletal muscle (around 300 milliseconds), and this is due to the activity of calcium (Ca⁺⁺ ) in the intracellular compartment.

The initial depolarization of cardiac muscle fiber depends on the entry of sodium (Na⁺) into the cell. However, for the action potential to occur and be maintained, Ca⁺⁺  must increase its cytoplasmic levels, which depends on:

  1. The increase in intracellular sodium induces the release of Ca⁺⁺ from the sarcoplasmic reticulum.
  2. Calcium entry from the extracellular space through the voltage dependent Ca⁺⁺ channels.
  3. The entry of extracellular Ca⁺⁺ causes the release of more Ca⁺⁺ ions by the sarcoplasmic reticulum, further increasing its intracellular concentration.

This is how the ion that guarantees the duration of the action potential of the cardiac muscle cell is the Ca⁺⁺.
