AI Thread Summary
Protein can be utilized for energy through amino acids entering glycolysis and the Krebs cycle, primarily via substrate-level phosphorylation and conversion to acetyl CoA. Understanding the specific pathways where amino acids integrate into these cycles is crucial for determining their energy contribution. The discussion emphasizes the importance of knowing the glycolysis and Krebs cycle mechanisms to assess protein's role in energy production. Additionally, the Calvin cycle is not directly involved in protein metabolism for energy. Overall, a solid grasp of metabolic pathways is essential for evaluating how proteins can serve as an energy source.

Can protein provide energy by using amino acids in the calvin cycle, by substrate-level phosphorylation, by putting acetyl co-a into krebs cycle, or by amino acids in glycolysis?

You need to show your own thoughts before you can receive help here.
 
Do you have the glycolysis and krebs cycles? If so, you've most likely been given something to determine where certain molecules enter. It should tell you where amino acids enter.
 
Thread 'Confusion regarding a chemical kinetics problem'
TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
