Answer:
The correct answer will be option-D.
Explanation:
Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.
Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.
This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.
Thus, option-D is the correct answer.
Answer:
Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... The contractile ring shrinks at the equator of the cell, pinching the plasma membrane inward, and forming what is called a cleavage furrow.

Answer:
True
Explanation:
A glucose molecule enters glycolysis in the cytoplasm of the cell. The glycolytic reactions break down one molecule of glucose into two molecules of pyruvate. Each of the pyruvate molecules is then decarboxylated and is oxidized into acetyl CoA. Acetyl CoA enters Kreb's cycle. Acetyl CoA is completely broken down into CO2 and H2O in Kreb's cycle. In this way, glycolysis and Kreb's cycle break down the glucose molecule into CO2 and H2O in a stepwise manner.
H S G Low temperature and High temperature.
When H is negative and S positive and G negative there will be spontaneous low temperature and spontaneous high temperature. When H is negative, and S is negative and temperature dependent then the low temperature will be spontaneous and high temperature will be non-spontaneous. When H is positive and S is positive then the temperature dependent and low temperature are non-spontaneous and high temperature will be spontaneous. When H will be positive and S is negative then G will be positive, the low temperature will be non-spontaneous and high temperature will also be non-spontaneous.
