Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
The jelly-like fluid that fills a cell is calledcytoplasm<span>. It is made up of mostly water and salt. </span>Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts.<span>Cytoplasm has various functions in the cell. </span>
Most of the important activities of the cell occur in the cytoplasm. Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.
<span>Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place. Without cytoplasm, the cell would be deflated and materials would not be able to pass easily from one organelle to another.</span>
Answer:
Explanation:
since during cellular respiration the carbon dioxide as well as the oxygen is provided through the food as a product of cellular respiration. therefore, energy from the food will be used after it leaves the mitochondrion during cellular respiration, through this the damage cell is repaired through cellular respiration.
