Answers:
A) The membranes of the Chloroplast are the
1) Thylakoid membrane 2) Envelope membrane
B) Calvin cycle occurs within the stroma, while light reactions occur within the thylakoid membrane.
Explanation:
Generally, the chloroplast is made up of the; <u>Thylakoid membrane and Envelop membrane</u>. The thylakoid membrane is basically the region for light absorption, thus making it the site for light reactions within the chloroplast.
Calvin cycle, which occurs in the stroma, involves light independent reactions. It occurs shortly after the light-dependent reactions, and further breaks down ATP and NADPH, products of the light reactions.
The stroma is located outside the thylakoid membrane.
For the remaining listed organelles:
1) The Cytosol- It’s the liquid space within the cell. The chloroplast can be found floating within the cytosol of any involved plant cell.
2) Thylakoid space- The space within the thylakoid.
Nurseries educate children about helping others that will help them to form strong bonds with others as they grow. It's better for young children to be introduced to a disciplined environment that helps them to learn social behaviors and skills and behave well with others.
Answer:
Explanation:
The molecular and cellular mechanisms and processes that explain muscle contraction in striated muscle occur in the myofibril sarcomere. Their understanding depends on the organization's understanding of the structure of the sarcomere. In an imaginary experiment we first assemble an ideal sarcomere.
Remember that the myofibril is a set of cylindrical compartments that are located next to each other, constituting an elongated cylinder. Each of these cylinders is a sarcomere and borders its neighbor on a line or band called, line or band z.
On each side of the z line, thin cylindrical filaments that are actin filaments are inserted. Each actin filament is formed by a double strand of actin molecules that are rolled over each other. In this organization, actin is called actin F.
