Answer:
I think it has to do with osmosis
Explanation:
Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.
When a cell is placed into distilled water, hypertonic solution takes place.
A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.
Photosynthesis is an important process in plants in which they produce glucose which serves them as food. This process occurs in the green leaves of the plants, thanks to the green pigment chlorophyll in the organelles known as chloroplasts.
If the question is what will happen to the plant, it will no longer have green leaves, and the rate of photosynthesis will be significantly decreased, but not stopped because there will probably be other pigments (non-green) able to <span>absorb sunlight.
</span> If the question is what will happen to <span>chloroplast if it is taken out of the cell and illuminated, i</span>ts pigment chlorophyll will absorb red and blue light,and reflects green light.
Answer:
Explanation:
An allosteric enzyme is one in which the activity of the enzyme can be controlled by the biniding of a molecule to the "allosteric site". This really just means somewhere other than the active site. Thus allosteric control of an enzyme can be classed in two ways. A positive allosteric modification is the binding of a molecule to the enzyme which increase the rate of reaction. Sort of like catalysing the catalysing effect of an enzyme. Obviously the opposite is true of negative allosteric modification. A good example for this is the activity of phosphofructokinase, which is promoted by a high AMP concentration, and inhibited by a high ATP concentration. This should make sense if you think about the action of a kinase etc.
