Which statement distinguishes the light-dependent (L-D) reaction from the light-independent (L-IND) reaction?
Alja [10]


The correct answer is  (a).

Both L-D and L-IND reactions take place in the chloroplast of the cell but in different parts or locations. L-D reactions take place in the chloroplast thylakoids while L-IND reactions take place in the chloroplast stroma.

Chloroplasts are chlorophyll- filled organelles mostly found in the leaves of green plants.  Chloroplasts are surrounded by a double membrane called the thykaloid membrane that forms long folds within the organelle. In electron micrographs, the thykaloid membranes look like stacked coins. Chlorophyll is located within the thykaloid membranes.

Between the thykaloid  membrane and the chloroplast membrane is a space. This space is what is called the stroma.

During depolarization, which of the following statements about voltage-gated ion channels is TRUE
Wewaii [24]

Answer:

In relation to voltage-gated ion channels, when depolarization occurs, Na⁺ gates open while K⁺ gates remain closed.

Explanation:

Depolarization is a phenomenon that occurs in cells like neurons, and depends on the distribution of ions in extracellular spaces and intraceluar.

  • Na⁺  is a predominantly extracellular cation.
  • K⁺ has a high intracellular concentration.

This distribution occurs when the membrane potential is at rest, with a negative intracellular value.

Depolarization involves opening the Na⁺ channels, so that this cation enters the intracellular space, causing a change in cell voltage. Increasing Na⁺ concentration in intracellular space progressively produces an action potential, resulting in an electrical signal.

While depolarization occurs, K⁺ channels remain closed, limiting the output of this cation to extracellular space, which would prevent the action potential from occurring.
