What else can I help you with?
What are true reactions of the Sun?
They are fusion reactions, and The force to get the reactions to occur comes from gravity.
Do exothermic reactions require any activation energy?
No activation energy can also be needed by endothermic reactions.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Enzymes are carbohydrates that act as catalysts in metabolic reactions true or false?
FALSE!Enzymes are PROTEINS that can act as catalysts in metabolic reactions.
What is true about most combustion reactions?
They release energy (they are exothermic).
What are true reactions of the Sun?
They are fusion reactions, and The force to get the reactions to occur comes from gravity.
Is it true that Enzymes are permanently changed by the reactions they catalyze?
true
Which are true of the reactions in the Sun?
a and b
Chemical reactions that occur in cells are called biochemical reactions?
yes. true.
What is true for all exergonic reaction?
One thing that is true for all exergonic reactions is that the reaction continues with a net release of what is called free energy. Exergonic reactions are chemical reactions.
Do exothermic reactions require any activation energy?
No activation energy can also be needed by endothermic reactions.
Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
Is blood clotting a chain of interlinked reactions?
Blood clotting is a chain of interlinked reactions.
Is Electrons in an excited state are more likely to enter into chemical reactions true?
True
Is it true that at equilibrium, no chemical reactions take place?
At equilibrium, the rates of the forward and reverse reactions are equal, but chemical reactions are still occurring.
Enzymes are carbohydrates that act as catalysts in metabolic reactions true or false?
FALSE!Enzymes are PROTEINS that can act as catalysts in metabolic reactions.
