Question

2.a You are investigating the aerobic catabolism of the amino acid alanine by using radioactively labeled alanine. During the first stage in the catabolism you find that radioactive pyruvate is formed. 2b n the above question (#3) no ATP is produced during the first stage. How many ATPs will be produced for each alanine which is catabolized through these 2 stages? a. e. 3. Which of the following statements concerning the rate of a reaction is correct? a. The activation energy (AG is sometimes negative b. For a reversible reaction, the activation energy (AG) can also affect the Ke eq c. The rate constant (k) is sometimes negative d. The rate often increases with increasing temperature None of the above

Explanation / Answer

Answer: Option B - 1

Cell undergoes respiration as per the below equation and produces one ATP.

Respiration: C6H12O6+6O2 ---> 6CO2+6H2O+ATP

Note: As per the guidelines we can answer only one question. So, I did not answer the remaining questions. Hope you can understand.
