_______________________ is a process that uses energy from nutrients to fuel an electron transport chain to make ATP.

검증된 단계별 안내

Identify the key components of the process described: it uses energy from nutrients, involves an electron transport chain, and results in the production of ATP.

Recall that the process which uses energy derived from nutrients to drive an electron transport chain for ATP synthesis is a fundamental metabolic pathway in cells.

Understand that this process involves transferring electrons through a series of membrane-bound proteins, creating a proton gradient that powers ATP synthase to generate ATP.

Recognize that this process is commonly known as 'cellular respiration' or more specifically 'oxidative phosphorylation' when referring to the electron transport chain and ATP synthesis step.

Conclude that the blank should be filled with the term describing this energy-conserving process, which is 'cellular respiration' or 'oxidative phosphorylation'.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cellular Respiration

Cellular respiration is the metabolic process by which cells convert nutrients, especially glucose, into usable energy in the form of ATP. It involves glycolysis, the Krebs cycle, and an electron transport chain, where energy from electrons is harnessed to produce ATP.

Electron Transport Chain (ETC)

The electron transport chain is a series of protein complexes located in the cell membrane (or mitochondrial membrane in eukaryotes) that transfer electrons from electron donors to acceptors. This transfer releases energy used to pump protons and create a gradient that drives ATP synthesis.

ATP Synthesis

ATP synthesis is the process of producing adenosine triphosphate (ATP), the cell’s main energy currency. In the electron transport chain, the proton gradient generated powers ATP synthase, an enzyme that synthesizes ATP from ADP and inorganic phosphate, providing energy for cellular activities.
