Describe the features of ATP that make it suitable for its role as the universal energy currency.
Suggest why ATP is required during protein synthesis.
Complete Table 6.1 with letters A to E from Fig. 6.1. Use each letter once, more than once, or not at all. Statements: • the site of the Krebs Cycle • a phospholipid bilayer impermeable to $\text{H}^+$ ions • the site of translation
Assume that the mitochondrion in Fig. 6.1 is cylindrical. Calculate the surface area of this mitochondrion. Use the formula: Surface area of cylinder $= 2\pi r^2 + 2\pi r h$. Show your working.
The inner membrane of the mitochondrion has a much larger surface area than the outer membrane because of the presence of cristae. Different cell types have different numbers of cristae in each mitochondrion. Cardiac muscle cells have mitochondria with a very large number of cristae. Suggest and explain why cardiac muscle cells have mitochondria with very large numbers of cristae.
