Answer:
The correct answer is option C, that is, increase the concentration of the enzyme. 
Explanation:
Biological molecules or proteins that enhance the rate of a chemical reaction taking place within the cell are known as enzymes. These proteins play an essential part in the proper functioning of the body, as they help in the process of metabolism and digestion.  
In the given case, if the enzyme gets saturated with the substrate, and is working at optimum pH and temperature, then to enhance the rate of the reaction the only thing that can be done is to enhance the concentration of the enzyme. However, further stimulation of some of the enzymes can be done with the addition of allosteric activators in the reaction, otherwise, enhancing the concentration of the enzyme is the only way.  
 
        
             
        
        
        
Answer:
True
Explanation:
This is because sacromere is the basic unit of cardiac muscles which is made up of thin and thick filaments. Cardiac muscle is consist of the contractile cells of the heart which it's appearance is striated as a result of alternating thick and thin filaments which is composed of myosin and actin. Actin and myosin are both firm contractile protein filaments, the actin form the thin filaments, and myosin form thick filaments.
