See how cells move energy with ATP, electrons, and gradients instead of memorizing pathways

Define free energy, reaction coupling, and the roles of ATP, NADH, and FADH2 as metabolic currency. Identify what it means to carry energy versus carry electrons.
2 lessonsTrace carbon and energy through glycolysis and the citric acid cycle. Compare why glycolysis makes some ATP and the citric acid cycle mostly produces reduced electron carriers.
2 lessonsExamine electron transport and chemiosmosis as the route to most ATP production, then connect light reactions to carbon fixation and apply regulation principles to pathway activity.
2 lessonsMetabolism starts with a basic problem: many cellular reactions do not proceed on their own, so cells must couple them to usable energy changes. This course builds a clear model of how ATP, NADH, glycolysis, the citric acid cycle, electron transport, chemiosmosis, photosynthesis, and regulation fit into that energy logic. It is designed for undergraduates who want to reason through metabolism on exams without getting lost in isolated steps.
The course covers free energy and reaction coupling, ATP and NADH/FADH2 as cellular currency, and the carbon and electron flow of glycolysis and the citric acid cycle. It also covers electron transport, proton gradients, ATP synthase, the light reactions and carbon fixation of photosynthesis, and the core principles that turn metabolic pathways on and off.
From project managers and operators to founders, analysts, and teams adopting AI, Fenzo is for people who want to get better at the work they already do.
Anything from using AI for project planning and analysis to improving workflows, decision-making, communication, and delivery. If you can describe the skill or task, Fenzo can build a course around it.
Yes. Tell Fenzo what you do, what you’re trying to accomplish, and where you’re stuck, and Fenzo will shape the course around your role, your goals, and the work you actually have to do.
No. Fenzo adapts to your starting point, so you can begin with the fundamentals or jump straight into more advanced work.
Yes. Fenzo for Business puts the whole team on one plan — shared seats, courses you can assign, and reporting on who has finished what.
See Fenzo for BusinessYou start by describing your goal or taking a short skill benchmark. Fenzo uses that context to identify gaps and shape the learning experience around them.

Something to operate in every section.
Three findings from decades of learning research shaped how every Fenzo lesson is built.

What the science says
Students in lecture-only classes are 1.5× more likely to fail.
How Fenzo does it
Every Fenzo lesson is interactive. No passive reading or watching, ever.

Skill retention over time · with vs. without practice
What the science says
Offloading thinking to AI erodes the very skills you’re trying to build.
How Fenzo does it
Fenzo makes you do the thinking — guided, but never done for you.

Long-term recall · retrieval vs. re-reading
What the science says
Recalling information beats re-reading it for building durable understanding.
How Fenzo does it
Lessons weave in quizzes and recall prompts, so it sticks.
