A.  If the optimum temperature for a cell's functions is exceeded, chemical reactions slow down as enzymes and other proteins begin to denature (change shape due to increased vibration of the atoms in the molecules that make up the proteins).
 
        
                    
             
        
        
        
The statement 'obtaining embryonic stem cells for use in therapy requires the destruction of embryos' would be used in an argument against the use of human embryonic stem cells for therapy. It is a type of stem cell therapy.
<h3>What are embryonic stem cells?</h3>
The embryonic stem cells are cells obtained from embryos that have the property to divide and specialize into different tissues.
The embryonic stem cells can be differentiated in the laboratory for the development of specific cell lineages.
The therapy using embryonic stem cells involves the use of these types of cells and the destruction of an embryo.

 The correct answer is C, Oxygen.
During aerobic cellular respiration, oxygen combines with hydrogen ions and water is released as a by-product of respiration. 
Explanation; 
Cellular respiration allows organisms to release energy stored in chemical bonds of glucose, and other nutrients. The energy in glucose or other nutrients such as fats is used to produce ATP, which cells use to supply their energy needs. During aerobic respiration (in presence of oxygen), oxygen is reduced and water is produced together with carbon dioxide as by-products.
