Question
Here is the "net" equation for a specific metabolic pathway:
Glucose + 2 ADP + 2 Pi + 2 NAD+ 2 Pyruvate + 2 ATP + 2NADH + 2 H+ + 2H2O
Which of the following statements apply to this pathway (as the equation is written, left to right)? Choose all that apply.
Question 1 options:
This pathway leads to the reduction of carbon in a monosaccharide and the oxidation of co-factors.
This is likely an anabolic pathway.
This pathway contains exergonic reactions which are used to form ATP.
This pathway contains endergonic reactions which require free energy from ATP.
This pathway results in the building of a bigger monosaccharide from smaller building blocks.
This is likely a catabolic pathway.
Match each statement about general principles with whether it applies to anabolism, catabolism or both.
Question 3 options:
1
Requires co-factors for enzymes
1
Reactions generally require energy and are coupled to ATP hydrolysis.
2
Breaks down complex molecules to simpler ones.
3
Results in the reduction of carbon in biomoleules and the oxidation of co-factors
2
Generally results in the release of free energy through exergonic reactions.
1.
Anabolism
2.
Catabolism
3.
Both
Which of these statements correctly applies to the concept of the "ATP cycle"?
Question 4 options:
During the ATP cycle, formation of ATP from ADP and Pi is coupled to other exergonic catabolic reactions.
During the ATP cycle, hydrolysis (breakdown) of ATP to ADP and Pi is commonly used for energy in catabolic pathways.
During the ATP cycle, formation of ATP from ADP and Pi is an exergonic process.
Cells in your body allow free energy consuming reactions to occur by coupling them with reactions which have a negative G.

lactate cOO HO-C-H COO C-O CH3 pyruvate NADH HExplanation / Answer
answer1)--This is likely a catabolic pathway,This pathway leads to the reduction of carbon in monosaccharide and oxidation of cofactors, This pathway conatins exergonic raections with formation of ATP.
Glucose forms pyruvate by the forward pathway which requires the energy from ATP and regeneration of NAD and ATP from ADP and NADH by the conversion of lactate to pyruvate with the help of lactate dehydrogenase.
answer3)-requires cofactors for enzymes--Both-3,reaction generally require energy and are coupled to ATP hydrolysis--2--catabolism, breaks complex molecules into simpler ones--2--catabolism,Results in the reduction of carbon in biomoleules and the oxidation of co-factors--2--catabolism,Generally results in the release of free energy through exergonic reactions--2--catabolism.
answer4)---During the ATP cycle, hydrolysis (breakdown) of ATP to ADP and Pi is commonly used for energy in catabolic pathways.
answer5)--True.
answer6)--all of these.
answer7)The production of larger molecules from smaller ones is generally a feature of:---anabolism.
answer8)The linking of an exergonic reaction to drive an endergonic reaction is called:---coupling.
answer9)Which molecule is getting oxidized in the chemical reaction shown above if the reactions proceeds according to the arrows?-----lactate.
The removal of hydrogen from lactate leads to the formation pyruvate with the help of enzyme lactate dehydrogenase and transfer to hydrogen to NAD + to from NADH and H+ ion.
