Q:

How do cells use water?

A:

Among other functions, water enables cells to transport chemicals, helps their temperature remain more stable and keeps the cells turgid. Every living cell on the planet requires water to survive, which is part of the reason scientists suspect that extraterrestrial life is most likely to occur on planets or moons with liquid water. Because water is used to flush toxins from the cell, it must be replenished frequently.

Because water is a polar molecule, it is an excellent solvent, and it can carry a wide variety of dissolved substances in it. This not only helps cells to transport dissolved substances within the cell, but also it helps them to absorb nutrients and expel wastes as well. When a cell is not properly hydrated, such transport functions slow, causing problems for the cell.

Because water has a relatively high specific heat value, it takes a lot of energy to heat up (and cool off), which means that cells do not experience drastic fluctuations in temperature. Stable temperatures help cells to perform more efficiently, as the functions of the cell often slow when the temperature falls and speed up when the temperature rises. Additionally, the water inside a cell helps the cell to remain somewhat pliable, while still retaining its shape.

    Why is ATP called the energy currency of the cell?

    A:

    ATP is called the energy currency of the cell, and of life, because it is the energy molecule that all cells need in order to do anything within the human body. The molecule is used like a battery within cells and allows the consumption of one of its phosphorous molecules.

  • Q:

    Which part of the chloroplast contains the Calvin cycle enzymes?

    A:

    The Calvin cycle takes place in the stroma of the chloroplast. Carbon dioxide enters the stroma of the chloroplast to combine with the five-carbon compound called ribulose1, 5-Biphosphate to form two molecules of a three-carbon compound called 3-Phosphoglyceric acid. This reaction is catalyzed by an enzyme called Ribulose bi-phosphate Carboxylase.
