Iron—cytochrome-c reductase

Iron—cytochrome-c reductase is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Iron—cytochrome-c reductase rather than just read about it. In short: In enzymology, an iron—cytochrome-c reductase (created 1972 as EC 1.9.99.1, transferred 2014 to EC 1.9.98.1) is an enzyme that catalyzes the chemical reaction ferrocytochrome c + Fe3+ ⇌ {\displaystyle \rightleftharpoons } ferricytochrome c + Fe2+ Thus, the two substrates of this enzyme are ferrocytochrome c and Fe3+, whereas its two products are ferricytochrome c and Fe2+. Classification This enzyme belongs to the f…

Key takeaways

Iron—cytochrome-c reductase belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Iron—cytochrome-c reductase to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Iron—cytochrome-c reductase from memory before moving on to harder problems.

Reference excerpt

In enzymology, an iron—cytochrome-c reductase (created 1972 as EC 1.9.99.1, transferred 2014 to EC 1.9.98.1) is an enzyme that catalyzes the chemical reaction

ferrocytochrome c + Fe3+ ⇌ {\displaystyle \rightleftharpoons } ferricytochrome c + Fe2+ Thus, the two substrates of this enzyme are ferrocytochrome c and Fe3+, whereas its two products are ferricytochrome c and Fe2+.

Classification This enzyme belongs to the family of oxidoreductases, specifically those acting on a heme group of donors with other acceptors.

Nomenclature The systematic name of this enzyme class is ferrocytochrome-c:Fe3+ oxidoreductase. This enzyme is also called iron-cytochrome c reductase.

Structure and function This enzyme is part of the electron transport system of Ferrobacillus ferrooxidans. It employs one cofactor, iron.

Worked examples

Example 1 — a first encounter with Iron—cytochrome-c reductase

Start with the simplest possible case. Write down what Iron—cytochrome-c reductase claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Iron—cytochrome-c reductase before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Iron—cytochrome-c reductase ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Iron—cytochrome-c reductase

In research: Iron—cytochrome-c reductase appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Iron—cytochrome-c reductase in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Iron—cytochrome-c reductase is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.9.98, Enzymes of unknown structure, Iron enzymes, so understanding it makes those chapters shorter.
In everyday life: Look for Iron—cytochrome-c reductase outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
