Question

Explain why the statement below about oxidative phosphorylation and substrate-level phosphorylation is either TRUE or FALSE.

Oxidative phosphorylation and substrate-level phosphorylation are similar processes that produce ADP but only differ in their mechanisms, efficiency, and oxygen dependence. Substrate-level phosphorylation is the primary ATP generator, while oxidative phosphorylation is just a supplementary process that transforms ATP into ADP.

Accepted Answer

FALSE because both processes produce ATP instead of ADP, and oxidative phosphorylation is the main ATP generator, while substrate-level phosphorylation is the supplementary process.

Answer

TRUE because both processes would produce ATP with minor differences in how this product is produced; also, oxidative phosphorylation is merely an additional mechanism that converts ATP into ADP; substrate-level phosphorylation is the main source of ATP.

Answer

FALSE because both processes produce NADP⁺ instead of ADP, and oxidative phosphorylation is the main NADP⁺ generator, while substrate-level phosphorylation is the process that also produces ATP.

Answer

FALSE because both processes produce glucose instead of ADP, oxidative phosphorylation is the main glucose generator, while substrate-level phosphorylation is also a process that also produces another product, sucrose.
