Question

Which of the following identifies the function of glycolysis within the entire process of cellular respiration?
Breaks down glucose into two pyruvate molecules
Reforms NAD+ and FAD to reuse in other parts of respiration
Sends energy-rich molecules to electron transport chain
Converts ADP to ATP for use as cellular energy

Answer 1

Clycolysis is the first part of cellular respiration, and don't give a lot ATP (net is 2), energy-rich molecules is not affected either (only 2 NADH + H is made). You can say that glycolysis the introduction to when the real energy is going to be harvested. So which one would you think?

Answer 2

well i thought it was D

Answer 3

Well you create 2 ATP in the glycolyse, while in the ECT you make about 26.

Answer 4

uhmm. im not clinically dyslexic but when it comes to biology i am haha can u explain it in dumbperson terms ?

Answer 5

Well I won't explain it in dumbperson terms becuase you are not ;)
The cellular respriation of glucose have 3 (in some literature 4) phases:
*Glycolysis
*Krebs cycle (citrat acid cycle)
*Electron Transport Chain (ETC) (sorry i did not write ETC in the first answer above)

In glycolysis, glucose is converted into another molecule or in order words prepaired to the Krebs cycle (a few ATP and NADH is created)

Krebs cycle uses the product from glycolysis to give electrons to the electron carriers (NAD) and will be carrieing them to the ETC. (a few ATP and a GDP is created)

Lastly, all the NAD from the Krebs cycle will be entering the ETC and create ATP. :)

Answer 6

Think you got the overview? :)

Answer 7

yes thanks. so can u help me understand my question ? i think its c or d

Answer 8

Well it is non of them. Glucose is made into two pyruvate molecules. The two pyruvate molecules then enters the Krebs cycle after some minor modifications.

Answer 9

okay i dont think iv learend about the krebs cycle yet. but okay

Answer 10

Well if you want to see the process of glycolysis you can see it here:

Answer 11

thanks. but what do u think it would be ?

Answer 12

It is A. "Breaks down glucose into two pyruvate molecules"

Answer 13

oh so i was completly wrong :/ well thanks

Answer 14

Mason is preparing to present the results of a study he did to track the germination rates of bean seeds treated with growth hormones. He wants to show the different rates of growth as they progressed over time. Which of the following would be best for conveying growth rates over time?
Simple table
Line chart
Venn diagram
Pie chart

Answer 15

You trid your self and that is what matters.

Answer 16

yeaa true. can u help me with this one ? i think its B

Answer 17

And you are absolutly right. :)

Answer 18

oh yay haha thanks

Answer 19

Or I would do the same if it was me with the study.

Answer 20

what do u mean ?

Answer 21

Never mind :) I ment if it was me who did that kind of study with plant growth under the effect of homones I would personaly do a line chart to show my results

Answer 22

oh okay lol
