The right answer is A) lower the activation energy of chemical reactions. 
The enzyme accelerates the reaction without changing the steady state.
Enzymes lower the activation energy of the substrate.
Activation energy or free activation energy is the energy that must be absorbed by the reagents to break their bonds.
The reagents must reach an unstable transition state in which the bonds are more fragile and easier to break.
Even an exergonic reaction requires the absorption of energy to reach the transition state.
 
        
                    
             
        
        
        
Answer:
Properties of life include the use of <u><em>energy</em></u> to power an organisms activities.
Explanation:
Energy is the driving force which allows every cell to perform its functions. Organisms like humans tend to gain energy by the process of cellular respiration. Cellular respiration can be described as a process in which organisms make carbon dioxide and water from glucose (from food) and oxygen (from air). Huge amounts of ATP is also released during this process. In plants, the process of photosynthesis and cellular respiration supplies them with the energy sources. 
 
        
             
        
        
        
Answer:
Invertebrates share four common traits:
They do not have a backbone. They are multicellular. All the cells have different responsibilities in keeping the animal alive. ... They reproduce by two reproductive cells, or gametes, coming together to produce a new organism of their species.
