Title: Glycolysis Inputs and Outputs Post by: dumakey1212 on Feb 21, 2013 Image: http://img208.imageshack.us/img208/1783/ghghc.png
Question: From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. Drag each compound to the appropriate bin. If the compound is not involved in glycolysis, drag it to the "not input or output" bin. Basically, it is asking to place the following compounds into one of three categories: NAD+, glucose, CO2, NADH, ATP, coenzyme A, Acetyl CoA, pyruvate, O2, ADP. The categories are net input (of glycolysis), net output (of glycolysis), and neither. I believe NAD+ and glucose are net input. I think CO2, NADH, ATP, coenzyme A, Acetyl CoA, and pyruvate are net output. I think O2 and ADP are neither. Could someone tell me if these are right. Clicking the image above is basically the easier way of reading this explanation, but the explanation is here for those who can't view the image. Thanks! Title: Re: Glycolysis Inputs and Outputs Post by: jmorales4 on Feb 21, 2013 The link reaction is:
2CH3COCOO- + 2NAD+ + 2H2O + CoA -->AcetylCoA + 2NADH + 2H+ + 2CO2 Net input = 2CH3COCOO-(pyruvate) + 2NAD+ + 2H2O + CoA Net output = AcetylCoA + 2NADH + 2H+ + 2CO Neither = ADP,ATP,O2,glucose. Title: Re: Glycolysis Inputs and Outputs Post by: acasto0871 on Feb 21, 2013 net input - nad+ , coenzyme A ,
net output - nadh , co2 , the above is the formation of one pyruvate to acetyl coa net input - 2 nad+ , 2 atp , 4 adp net output - 2 nadh , 2 adp , 2 h2o , 4atp the above is the formation of pyruvate from a glucose molecule combine them and you get glucose to pyruvate to acetyl coa Title: Re: Glycolysis Inputs and Outputs Post by: sarah.brush on Feb 21, 2013 Inputs = O2, ADP, NAD+, Glucose
Outputs = NADH, ATP, Pyruvate, Acetyl COa, and CO2 Neither = Coenzyme A Title: Re: Glycolysis Inputs and Outputs Post by: dumakey1212 on Feb 21, 2013 Glucose is not an input of glycolysis...?
Title: Re: Glycolysis Inputs and Outputs Post by: kapeshia on Feb 21, 2013 Net input: NAD+, ADP, Glucose, O2.
Net output: ATP, NADH, CO2. Neither: Acetyl CoA, Pyruvate ( not net input or net output, they are intermediate during the process of cellular respiration). CoEnzyme A could be considered as net input and net output, cause it enters the process and leave it as it is, cause enzymes help in the process and never consumed.

NET INPUT- NAD+, ADP, GLUCOSE NET OUTPUT ATP, PYRUVATE, NADH neither = acetyl CoA, CO2 and O2 ( these are involved in the TCA and ETS..NOT glycolysis Title: Re: Glycolysis Inputs and Outputs Post by: biolove on Feb 21, 2013 net input - acetyl CoA, NADH, ADP
net output - 1 xATP,NAD+,CO2, CoA, neither - pyruvate,O2,glucose Title: Re: Glycolysis Inputs and Outputs Post by: dumakey1212 on Feb 21, 2013 referring ONLY to glycolysis which is an anaerobic process NET INPUT- NAD+, ADP, GLUCOSE NET OUTPUT ATP, PYRUVATE, NADH neither = acetyl CoA, CO2 and O2 ( these are involved in the TCA and ETS..NOT glycolysis ADP is an input of glycolysis? Title: Re: Glycolysis Inputs and Outputs Post by: adamant363 on Feb 21, 2013 NET INPUT- NAD+, ADP, GLUCOSE
NET OUTPUT ATP, PYRUVATE, NADH Title: Re: Glycolysis Inputs and Outputs Post by: bio_man on Feb 21, 2013 referring ONLY to glycolysis which is an anaerobic process NET INPUT- NAD+, ADP, GLUCOSE NET OUTPUT ATP, PYRUVATE, NADH neither = acetyl CoA, CO2 and O2 ( these are involved in the TCA and ETS..NOT glycolysis ADP is an input of glycolysis? I believe it is, because it is required to regenerate ATP. Title: Re: Glycolysis Inputs and Outputs Post by: bobaholic on Feb 22, 2013 it's the first step of cellular respiration
you produce: 2 pyruvate for the citric acid cycle 4 ATP (with a net of 2 ATP) 2 NADH Title: Re: Glycolysis Inputs and Outputs Post by: Watersyle03 on Feb 23, 2013 there are 10 step in the process of glycolysis.. u alway start with glucose and end with pruvate

Title: Re: Glycolysis Inputs and Outputs Post by: Solomonstime on Oct 7, 2013 Why is every single answer different from one another; so which one is actually the right answer?
Title: Re: Glycolysis Inputs and Outputs Post by: bio_man on Oct 7, 2013 Topic isn't solved, so your guess is as good as theirs.
Title: Re: Glycolysis Inputs and Outputs Post by: softballer on Oct 9, 2013 Let me try to bring all these replies together.
Glycolysis begins with the phosphorylation of glucose by ATP in two steps, so two ATP are input. two Water molecules are produced from 2-phosphoglycerate to form PEP. Nad+ is an input NADH is an output Pyruvate is an output-the oxidation of pyruvate, which does release CO2 and NADH, is considered to be a transition to the Krebs cycle, so is not a part of glycolysis/ Therefore, In glycolysis, ATP is both an input and output.ADP is an input. NAD+ is an input and NADH is an output. Finally, Pyruvate is an output as is water. The rest of the substances mentioned do not come into play in glycolysis. Title: Re: Glycolysis Inputs and Outputs Post by: LaurenBurns123 on Oct 12, 2013 referring ONLY to glycolysis which is an anaerobic process NET INPUT- NAD+, ADP, GLUCOSE NET OUTPUT ATP, PYRUVATE, NADH neither = acetyl CoA, CO2 and O2 ( these are involved in the TCA and ETS..NOT glycolysis This is the correct answer Title: Re: Glycolysis Inputs and Outputs Post by: callmedoc on Oct 23, 2013 Well most of ya'll were wrong because I just looked at this for my homework because I couldn't find it in the book or the video shown and it was wrong.
Title: Re: Glycolysis Inputs and Outputs Post by: bio_man on Dec 4, 2013 net input - nad+ , coenzyme A , net output - nadh , co2 , the above is the formation of one pyruvate to acetyl coa net input - 2 nad+ , 2 atp , 4 adp net output - 2 nadh , 2 adp , 2 h2o , 4atp the above is the formation of pyruvate from a glucose molecule combine them and you get glucose to pyruvate to acetyl coa I don't think that's correct. Title: Re: Glycolysis Inputs and Outputs Post by: conor on Jan 28, 2014 referring ONLY to glycolysis which is an anaerobic process NET INPUT- NAD+, ADP, GLUCOSE NET OUTPUT ATP, PYRUVATE, NADH neither = acetyl CoA, CO2 and O2 ( these are involved in the TCA and ETS..NOT glycolysis Thanks!!! you were the only one on here with the right answer. Everyone else is just stupid Title: Re: Glycolysis Inputs and Outputs Post by: PrincessSarah on Mar 10, 2014 Net Input: glucose, ADP, NAD+
Net Output: Pyruvate, ATP, NADH Not Input or Output: O2, CO2, acetyl CoA, coenzyme A Title: Re: Glycolysis Inputs and Outputs Post by: sara2 on Mar 11, 2014 I just did this question, and i got it right.
Input: Nad+, ADP, Glucose Output: ATP, pyruvate, nadh Neither: Acetyl CoA, CO2, O2, coenzyme A Title: Re: Glycolysis Inputs and Outputs Post by: Hershey on Apr 21, 2014 Simply put:
The net input: glucose, ADP, & NAD+ The net output: pyruvate, ATP, NADH Not input or output: O2, CO2, acetyl CoA, coenzyme A Also posted by sara2 would I obviously agree with. I would attach an image but I am technologically deficient. Title: Re: Glycolysis Inputs and Outputs Post by: revidouch on May 28, 2014 Thanks a lot!
