If a red blood cell is placed in a hypertonic solution, the cell would shrink.
Hypertonic solution means that the solution has a lower water potential than the other side (which is the cell's cytoplasm in this case), and by that, water molecules would have a tendency to flow from a region of higher water potential to a region of lower water potential. This movement of water molecules is called osmosis. But note that a semi-permeable membrane (a membrane which can decide what substances can go in and out, the cell membrane is an example) has to be present in osmosis, or else the movement may be regarded as diffusion.
As the water molecules flowed away from the red blood cell cytoplasm, the cell loss so much water that the membrane has nothing much to hold and thus the cell shrinks.
Answer: The correct answer would be lactic acid fermentation.
Explanation:
In humans, specially in muscle cells, lactic acid fermentation takes place during high intensity exercise. During exercise when oxygen supply fails to meet the demands of muscle, they undergo lactic acid fermentation instead of cellular respiration.
During this process, the pyruvate (end product of glycolysis) is converted into the lactate with the help of enzyme lactate dehydrogenase.
It regenerates NAD⁺ lost in the glycolysis and thus, helps in continuous working of glycolysis.
Balanced blood sugar helps keep our brain healthy, our energy levels stable and our mood balanced. However, when disrupted, our blood sugar can lead to increased sugar cravings, irritability, poor sleep, brain fog, anxiety, low energy and weight gain, and in the longer term, diabetes
Answer:
Photosynthesis releases oxygen once the whole procedure is done and produces most common glucose carbohydrate molecules.
