Answer:
Explanation:
Normally, under anaerobic condition in yeast, pyruvate produced from glycolysis leads to the production of ethanol as shown below.
pyruvate ⇒ acetaldehyde + NADH ⇒ ethanol + NAD
The pyruvate is converted to acetaldehyde by the enzyme, pyruvate decarboxylase. It should be NOTED that carbon dioxide is released in this step. The acetaldehyde produced in the "first step" is then converted to ethanol by the enzyme alcohol dehydrogenase. It must be noted from the above that the steps are irreversible.
If a mutated strain of yeast is unique because it does not produce alcohol and lactic acid (which is referred to as toxic acid in the question); thus having a high level of pyruvate because of the presence of a novel enzyme.   <u>The function of this novel enzyme will most likely be the conversion of acetaldehyde in the presence of carbondioxide back to pyruvate; thus making that step reversible</u>. This could be a possible explanation for the high level of pyruvate present in the yeast.

The  terminal  cisternae  releases  calcium  ion
  The  terminal  cisternae   act  as   calcium  storage  sites.  The  calcium  ions  stored in  the  terminal  cisternae  are  essential  in  muscle   contraction. The  calcium  release  unit  of  muscle  consists of  terminal  cisternae  of  the  sarcoplasmic  reticulum  and  it  is  adjacent  transverse  or T-  tubule  that  is  the  invaginated  part  of  the  surface  membrane.
