In short: FLN Tutors gives biochemistry help and online tutoring from A-Level to postgraduate level. Tutors explain biomolecules, protein structure, enzymes and Michaelis–Menten kinetics, metabolic pathways and their regulation, molecular biology, buffers and spectrophotometry step by step, and help you analyse lab data and write reports in your own words. Matched to a verified specialist who knows your course, your university's marking criteria, and your deadline.
Topics we cover
FLN biochemistry tutors help university students with metabolic pathways, enzyme kinetics, protein structure, molecular biology and laboratory techniques. Sessions connect the chemistry to the biology so pathways make sense rather than being memorised.

Biochemistry help is one-to-one support from a tutor who explains the chemistry of living things: the structure and function of biomolecules, how enzymes work, how cells extract and use energy, and how genetic information is expressed. It is a core subject in biochemistry, biomedical science, medicine, pharmacy and biology degrees.

This map lists the core biochemistry topics, the point where students most often get stuck, and how a tutor helps you past it.
| Topic | Where students get stuck | How a tutor helps |
|---|---|---|
| Biomolecules | Linking structure to function | Draw structures and explain each property |
| Protein structure | Primary to quaternary structure and folding | Bond types mapped to each level |
| Enzymes | Mechanisms and inhibition types | Lineweaver–Burk plots interpreted together |
| Enzyme kinetics | Km, Vmax and calculations | Worked Michaelis–Menten examples |

Tutors cover the full biochemistry syllabus.
| Area | Topics |
|---|---|
| Biomolecules | Carbohydrates, lipids, amino acids, nucleotides |
| Proteins | Structure, folding, haemoglobin and myoglobin, protein purification |
| Enzymes | Catalysis, kinetics, inhibition, allosteric regulation |
| Metabolism | Glycolysis, the citric acid cycle, oxidative phosphorylation, gluconeogenesis, fatty acid metabolism |
| Regulation | Hormonal control, signalling pathways, integration of metabolism |
| Molecular biology | DNA replication, transcription, translation, gene regulation |
| Techniques | Chromatography, electrophoresis, spectrophotometry, PCR, western blotting |
An illustrative enzyme has Vmax = 100 µmol/min and Km = 2 mM. Find the reaction rate at two substrate concentrations, using v = Vmax[S] ÷ (Km + [S]).
| [S] | Working | v |
|---|---|---|
| 2 mM | 100 × 2 ÷ (2 + 2) | 50 µmol/min (half of Vmax, as [S] = Km) |
| 6 mM | 100 × 6 ÷ (2 + 6) | 75 µmol/min |
Km is the substrate concentration at half Vmax, so a lower Km means a higher apparent affinity. A competitive inhibitor raises the apparent Km without changing Vmax.
Two lab calculations. Illustrative values only.
| Question | Working | Answer |
|---|---|---|
| An acetate buffer (pKa 4.76) has twice as much acetate as acetic acid. Find the pH. | pH = pKa + log₁₀([A⁻] ÷ [HA]) = 4.76 + log₁₀ 2 | ≈ 5.06 |
| A sample has absorbance 0.45 in a 1 cm cuvette. ε = 15,000 M⁻¹ cm⁻¹. Find the concentration. | A = εcl, so c = 0.45 ÷ (15,000 × 1) | 3.0 × 10⁻⁵ M (30 µM) |
The Henderson–Hasselbalch equation works best when the ratio is between about 0.1 and 10, which is the useful buffering range.
Students often find metabolism overwhelming because of the number of steps. Tutors focus on the logic: where each pathway happens, its inputs and outputs, its key regulated enzymes and how pathways connect in fed and fasting states.
Tutors match your level, syllabus and exam board, from school to PhD.
| Level | What you study | Matching help |

Most lost marks come from vague mechanisms and calculation slips.
| Mark-loser | What to do instead |
|---|---|
| Listing pathway steps without regulation | Name the key regulated enzymes and how they are controlled |
| Confusing types of enzyme inhibition | Compare their effects on Km and Vmax |
| Unit errors in kinetics and Beer–Lambert | Keep units through each step |
| Describing graphs without explaining them | Explain the biochemistry behind each trend |
| Mixing up DNA and RNA processes | Use a step-by-step sequence for each |
| Old or unreferenced sources | Use current textbooks and research |
Biochemistry is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Exams | Accurate mechanisms, structures and calculations |
| Data-interpretation questions | Correct analysis of kinetics plots, gels and spectra |
| Lab reports | Accurate data processing, graphs and discussion |
| Essays | A focused argument using current research |
| Research projects | A clear hypothesis, sound methods and well-reported results |
Biochemistry students use lab and analysis tools.
| Tool | What it is used for |
|---|---|
| Spectrophotometers | Measuring absorbance for assays |
| GraphPad Prism or Excel | Kinetics curves, standard curves and statistics |
| PyMOL or ChimeraX | Viewing protein structures |
| Protein Data Bank (PDB) | Free 3D protein structure data |
| NCBI and UniProt | Sequence and protein databases |
Biochemistry is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where biochemistry is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | A-Level Biology and Chemistry, BSc Biochemistry | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | Harvard or a journal style |
| United States | AP Biology, college biochemistry, pre-med | Letter grades A–F and a 4.0 GPA scale | APA, CSE or ACS |
| Australia | BSc biochemistry units | HD, D, C, P at university; ATAR for school leavers | Harvard or APA |
| Canada | BSc Biochemistry | Letter grades or percentages; GPA scales vary by province and university | APA or CSE |
| India | BSc and MSc Biochemistry, MBBS biochemistry | Board exam percentages; university CGPA, often on a 10-point scale | As your university specifies |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of biochemistry help depends on the topic, the type of task and your deadline. A set of kinetics calculations costs less than a full referenced lab report. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Student reviews
Used FLN Tutors? Be one of the first to share how it went, in writing or in a short video.
Yes. Tutors explain the biochemistry behind each question and work through calculations step by step, so you can solve similar questions yourself.
It describes enzyme rate: v = Vmax[S] ÷ (Km + [S]). Vmax is the maximum rate and Km is the substrate concentration giving half of Vmax.
Km is the substrate concentration at half Vmax. A lower Km means the enzyme reaches half its maximum rate at a lower substrate concentration.
A competitive inhibitor competes for the active site, raising apparent Km but not changing Vmax; a non-competitive inhibitor binds elsewhere and lowers Vmax.
pH = pKa + log₁₀([A⁻] ÷ [HA]). Substitute the pKa and the ratio of conjugate base to acid to find the buffer pH.
Absorbance A = εcl, so concentration c = A ÷ (εl), with ε the molar absorption coefficient and l the path length.
Primary is the amino acid sequence, secondary is local folding such as α-helices and β-sheets, tertiary is the overall 3D shape and quaternary is the arrangement of several chains.
Learn where each pathway happens, its overall inputs and outputs and its regulated steps, then link pathways together rather than memorising every intermediate first.
Glycolysis breaks glucose down to pyruvate, releasing energy; gluconeogenesis builds glucose from non-carbohydrate sources and uses different enzymes at the irreversible steps.
The electron transport chain pumps protons across the inner mitochondrial membrane, and ATP synthase uses the proton gradient to make ATP.
Yes. Tutors help you process data, draw graphs and write a clear discussion. See lab report help.
Yes. Tutors cover DNA replication, transcription, translation and gene regulation.
