L-lactate dehydrogenase (cytochrome)

L-lactate dehydrogenase (cytochrome) is a biology 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 L-lactate dehydrogenase (cytochrome) rather than just read about it. In short: In enzymology, L-lactate dehydrogenase (cytochrome) (EC number 1.1.2.3) is an enzyme that catalyzes the chemical reaction The substrate of this enzyme is (S)-lactic acid, which is acted on by two equivalents of the cofactor, ferricytochrome c, which oxidises the hydroxy group to a keto group, giving pyruvic acid, while the cofactor's iron is reduced.

Key takeaways

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

Reference excerpt

In enzymology, L-lactate dehydrogenase (cytochrome) (EC number 1.1.2.3) is an enzyme that catalyzes the chemical reaction

The substrate of this enzyme is (S)-lactic acid, which is acted on by two equivalents of the cofactor, ferricytochrome c, which oxidises the hydroxy group to a keto group, giving pyruvic acid, while the cofactor's iron is reduced.

See also D-lactate dehydrogenase (cytochrome) which acts on the enantiomer of the substrate

Worked examples

Example 1 — a first encounter with L-lactate dehydrogenase (cytochrome)

Start with the simplest possible case. Write down what L-lactate dehydrogenase (cytochrome) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 L-lactate dehydrogenase (cytochrome) 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 L-lactate dehydrogenase (cytochrome) 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 L-lactate dehydrogenase (cytochrome)

In research: L-lactate dehydrogenase (cytochrome) appears in biology 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 L-lactate dehydrogenase (cytochrome) 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: L-lactate dehydrogenase (cytochrome) is common in secondary-school and first-year university syllabi. It links to neighbouring topics EC 1.1.2, EC 1.1 stubs, Enzymes of unknown structure, so understanding it makes those chapters shorter.
In everyday life: Look for L-lactate dehydrogenase (cytochrome) 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.
