During cellular respiration, the covalent bonds of a molecule are broken down to form products. Which molecule is broken down?
ADP
carbon dioxide
water
sugar***
During cellular respiration, four total ATP are produced when pyruvic acid is created. What else is produced as a result of this reaction?
heat***
sugar
oxygen
water
Why does hydrogen bond so tightly to oxygen during cellular respiration?
It is more electronegative than oxygen.
It is not electronegative, but oxygen is.
It is less electronegative than oxygen.***
It is electronegative, but oxygen is not.
What is the byproduct of anaerobic respiration?
carbon dioxide
pyruvic acid
lactic acid***
oxygen
Which statement correctly describes what transpires during a chemical reaction?
A catalyst strengthens the bonds of the reactants increasing the activation energy.
A catalyst weakens the bonds of the reactants increasing the activation energy.
A catalyst strengthens the bonds of the reactants lowering the activation energy.
A catalyst weakens the bonds of the reactants lowering the activation energy.***
So this is what mine looked like
1) During cellular respiration, the covalent bonds of a molecule are broken down to make products. Which molecule is broken down?
*Sugar
2) During cellular respiration, four total ATP pyruvic acid is created. What else is produced as a result of this reaction?
*Heat
3)Why does hydrogen bond so tightly to oxygen during cellular respiration?
*It is less electronegative than oxygen
4) Identify the byproduct of lightning acid fermentation.
*Lactic acid
5) When a reaction releases more energy than it uses, it is called?
*Exothermic

Unit 5 Lesson 9
he's fr correct up there i got a 100 the last question was different for me the answer for Conexus kids is B. exothermic
All correct, 100% :)
Nunya & Taylor are right I got a 100%
thank you. taylor you were correct on the last one
all good! and im in connexus and taylor is right
Just helping is 100% correct
just helping helped me :D thanks y'all!
(Cellular respiration quick check)
1) sugar
2) heat
3) It is less electronegative than oxygen
4) lactic acid
5) exothermic
