Using Fig. 7.1, state the letter that shows the location of: the Krebs cycle; oxidative phosphorylation; decarboxylation.
Suggest one function of the circular DNA shown in Fig. 7.1.
Complete the table below by listing three substances that enter the mitochondria and three substances that leave the mitochondria.
Cyanide poison combines with cytochrome oxidase, a carrier in the electron transport system. Suggest how cyanide ingestion by humans causes death through muscle failure.
Tripalmitin is a triglyceride. The equation for the aerobic respiration of tripalmitin is $2\text{C}_{51}\text{H}_{98}\text{O}_6 + 145\text{O}_2 \rightarrow 102\text{CO}_2 + 98\text{H}_2\text{O}$. Calculate the RQ value for tripalmitin. Give your answer to 2 decimal places. Show your working.
Explain why the normal RQ value for respiration in humans lies between 0.7 and 1.0.
