Answer:
False. When bonds are broken, energy is absorbed.
Explanation:
Atoms form bonds to seek stability, which means lower energy compared to when they were separated. This means that separating atoms by breaking bonds is not energetically favourable.
Therefore, in order to break a chemical bond we need to provide energy to the system, which makes the process endothermic (it absorbes energy).
The attached image shows an energy diagram for the H₂ molecule, showing the variation in energy during bond formation.

hope is helpful even tho i think you dont need it, i needed and maybe someone else too
transform into a sugar that causes a reaction in a substrate.
bind to a substrate and cause a reaction in the substrate.,
stimulate other molecules to become substrates.
Answer:
bind to a substrate and cause a reaction in the substrate.,
Enzymes, which are sensitive to their environment, can become denatured and lose their functional shape if temperatures are too high. This prevents them from binding to and initiating a reaction in the substrate.
Enzymes are extremely sensitive to their environment, including conditions like temperature and pH. If the environment of an enzyme becomes too hot, it can cause the enzyme to denature, or lose its functional shape. This distorts the active site of the enzyme, which is the region where the substrate, or molecule the enzyme acts upon, binds. Consequently, a denatured enzyme cannot perform its core function, which is to bind to a substrate and cause a reaction in the substrate. If the enzyme cannot bind to the substrate, it cannot catalyze the reaction. Therefore, extreme heat can inhibit the functioning of enzymes.

with fewer contractions
the contractions would suddenly cease
with the same frequency of contractions
Correct answer: B). With fewer contractions
The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.
But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.
