Question
Which step in cellular respiration produces the most ATP?
glycolysis
electron transport chain
lactic acid fermentation
glycolysis
electron transport chain
lactic acid fermentation
Answers
GPT-4o mini
The step in cellular respiration that produces the most ATP is the **electron transport chain**. During this stage, a large amount of ATP is generated through oxidative phosphorylation as electrons are transferred through a series of proteins in the inner mitochondrial membrane. Glycolysis and lactic acid fermentation produce significantly less ATP compared to the electron transport chain.

What is the activation energy of a reaction? (1 point)
the minimum energy required by the reactants for the reaction to proceed
the amount of energy lost
the minimum energy required by the reactants for the reaction to proceed
the amount of energy lost
GPT-4o mini
The activation energy of a reaction is defined as **the minimum energy required by the reactants for the reaction to proceed**. This energy is necessary for the reactants to reach the transition state and allows the reaction to occur.

Which statement best describes activation energy? (1 point)
It is the energy the reactants must be given in order for a reaction to occur.
It is the energy the reactants need to release in order for a reaction to occur.
It is the energy the reactants must be given in order for a reaction to occur.
It is the energy the reactants need to release in order for a reaction to occur.
GPT-4o mini
The statement that best describes activation energy is: **It is the energy the reactants must be given in order for a reaction to occur.** Activation energy is the energy threshold that must be overcome for the reactants to transform into products.

Which could make a source unreliable? (1 point)
Only non-experts corroborate the data in an article.
There are some typos in an article.
Only non-experts corroborate the data in an article.
There are some typos in an article.
GPT-4o mini
The option that could make a source unreliable is: **Only non-experts corroborate the data in an article.**
While typos can indicate a lack of attention to detail, the credibility of the data is more fundamentally impacted by the expertise of those corroborating it. If the corroborating individuals are not experts in the field, the reliability of the information may be questioned.

What process must occur for carbon, hydrogen, and oxygen atoms from sugar molecules to combine with other elements to form amino acids?
Sugar molecules must undergo hydrolysis so they can react with nitrogen to form amino acids.
Sugar molecules must be rearranged through metabolic pathways to form amino acids.
Sugar molecules must undergo hydrolysis so they can react with nitrogen to form amino acids.
Sugar molecules must be rearranged through metabolic pathways to form amino acids.
GPT-4o mini
The correct statement is: **Sugar molecules must be rearranged through metabolic pathways to form amino acids.**
While hydrolysis is a process that breaks down molecules, in this context, the sugar molecules must be converted and rearranged through various metabolic pathways to form amino acids, which involves incorporating nitrogen and other elements.
