How do enzymes act as catalysts? (Choose ALL that apply) They allow for fewer collisions of molecules (enzymes + substrates) The
vazorg [7]

Answer:

- They allow for more collisions of molecules (enzymes + substrates)

- They lower the amount of activation energy needed to complete the reaction.

- They speed up chemical reactions to form more products

Explanation:

Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).

Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.

Explain the chemical properties that cause water to have a relatively high specific heat and how that, in turn, affects water's
RideAnS [48]
Water is a polar molecule bcz oxygen bears partial negative charhe and hydrogen bears partial positive charge. This results in extensive hydrogen bonding btween water molecules. The temperature is another way of saying the average kinetic energy of gases liquids or vibration for the case of solids. The Heat Capacity is the ability of matter to absorb thermal energy. Water's specific heat is defined as one. Water has high heat capacity because it can store heat in many ways. Which makes its capacity higher than anything
