I think it might be metaphase because all of the chromosomes are lined up in the middle :) either that or anaphase!
For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.
Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.
In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.

cardiac muscle require lot of energy to perform while skeletal muscle are used in coordinate of bone moments so they require less energy since mitochondria is powerhouse cell so it is highly concentrated in cardiac muscle...
The correct answer is all fo the above
