Which is true about enzymes is: enzymes increase the rate of reactions by lowering the activation energy barrier.
Enzymes are chemical compounds in the form of proteins that act as biocatalysts which function to speed up reactions.
Enzymes work specifically, that is, they can only work on certain substrates by adjusting the shape of the substrate. Enzymes sensor with molecules for substrates to produce compounds through organic chemical reactions that require energy. Some of the reactions assisted by enzymes such as the breaking of large molecules into small ones or the binding of molecules into new molecules. Enzymes can do that because of the influence of the activation energy that every chemical reaction has.
Activation energy is the energy required to break down the reactants. The role of enzymes is to lower the activation energy limit needed to start reactions.

#SPJ4
A plant cell is rectangular, while an animal cell is circular.
Answer:
Letter A represents the greatest potential energy.
Letter C represents the least potential energy.
Letter C represents the greatest kinetic energy.
Letter A represents the least kinetic energy.
Letters A and C represent an equal amount of both potential and kinetic energy.
Explanation:
Potential energy is a put away energy that relies on the overall situation of different pieces of a framework. A spring has progressively potential energy when it is packed or extended. A steel ball has more potential energy raised over the ground than it has in the wake of tumbling to the Earth. In the raised position it can do more work. Potential energy is a property of a framework and not of an individual body or molecule; the framework made out of the Earth and the raised ball, for instance, has progressively potential energy as the two are more distant isolated.\
Kinetic energy is a type of energy that an article or a molecule has by reason of its movement. In the event that work, which moves energy, is done on an item by applying a net power, the article accelerates and along these lines increases kinetic energy. Kinetic energy is a property of a moving item or molecule and depends on its movement as well as on its mass. The sort of movement might be interpretation (or movement along a way starting with one spot then onto the next), turn about a pivot, vibration, or any blend of movements.
