Questions about the Enzyme Kinetics poster

What’s on the Enzyme Kinetics poster?
The rule, 3 worked examples, and the mistake everyone makes. Reaction rate rises with substrate concentration until the enzyme is saturated.; v = (Vmax × [S]) ÷ (Km + [S]); Low Km = High affinity for substrate; High Km = Low affinity; Vmax = Rate when fully saturated; Common mistake: Reading Km as a rate → Km is a concentration. Competitive inhibitors raise Km and leave Vmax unchanged. Non-competitive inhibitors lower Vmax and leave Km unchanged.
Who is the Enzyme Kinetics poster for?
Enzyme Kinetics belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning biochemistry can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Enzyme Kinetics poster?
Km is the substrate concentration at half maximum rate. Low Km means high affinity. A wall chart earns its place by being glanceable from where the work is happening, so Enzyme Kinetics belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
What other posters go with Enzyme Kinetics?
Amino Acids, ATP and Food Tests sit alongside Enzyme Kinetics in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Amino AcidsATPFood Tests
Is the Enzyme Kinetics poster free to download and print?
Yes. Enzyme Kinetics downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Enzyme Kinetics poster print at?
Enzyme Kinetics is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Enzyme Kinetics loses nothing.Printing guide
