Answer:
Osmosis
Explanation:
Osmosis is a the movement of solvent, water, across a membrane from an area where there is low solute concentration to an area of high solute concentration.
Please note that a solute concentration simply refers to the quantity of solute that have been able to dissolve in a solution or solvent.
Let me add that OSMOSIS is a type of DIFFUSION. This mostly demonstrated in a salt-water solution.
A common Example of osmotic phenomenal is:
Soaking bread in tea, soak a piece of foam in water etc.
A whole number ratio; Hopefully that is the answer if you need an actual number the best guess would be 2:1.
Answer:
a) both processes first break down glucose into pyruvic acid
Explanation:
Cellular respiration is the process through which cells of living organisms derive their energy. Cellular respiration can be carried out with oxygen (aerobic) or without oxygen (anaerobic). The oxygen actually acts as a final electron acceptor in the last stage of aerobic respiration process (ETC).
Cellular respiration starts with GLYCOLYSIS, which is the process whereby glucose is broken down to pyruvic acid. Glycolysis occurs in the cytoplasm and does not require oxygen to occur. In a complete respiration, the step progresses into the Kreb's cycle and Oxidative phosphorylation, which occurs in the mitochondria.
Hence, GLYCOLYSIS (break down of glucose to pyruvic acid) is a common process to both aerobic and anaerobic.
Catalysts lower the Activation energy for reactions. The lower the activation energy for a reaction,the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrate ms bind.
