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.
In cells endergonic reactions are often coupled with enzymatic reactions that store energy True or false?
false
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 combustion reactions?
Carbon dioxide will be a product. APEX: These reactions are always redoxx reactions. The products will always be carbon dioxide and water.
What are true reactions of the Sun?

Is it true that Enzymes are permanently changed by the reactions they catalyze?
true
Chemical reactions that occur in cells are called biochemical reactions?
yes. true.
Which are true of the reactions in the Sun?
a and b
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.
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.
Do exothermic reactions require any activation energy?
No activation energy can also be needed by endothermic reactions.
Is blood clotting a chain of interlinked reactions?
Blood clotting is a chain of interlinked reactions.
Is it true or false that Chemical reactions rearrange atoms but do not create or destroy them?
true
Is it true that catalyst speed chemical reactions but are not changed by them?
Yes, it's true.
In cells endergonic reactions are often coupled with enzymatic reactions that store energy True or false?
false
