The Claim
Inhibition of mitochondrial lactate dehydrogenase with malonate in rat hippocampal slices suppresses neuronal function under both lactate- and glucose-supported conditions, demonstrating that lactate must be converted to pyruvate to serve as an energy substrate.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When the enzyme that converts lactate to pyruvate is blocked in rat brain tissue slices, neurons stop functioning properly even when lactate or glucose is available as fuel, showing that lactate must be turned into pyruvate to be used for energy.
See the scientific wording
In rat hippocampal slices, inhibition of mitochondrial lactate dehydrogenase with malonate suppresses neuronal function under both lactate- and glucose-supported conditions, indicating that lactate must be converted to pyruvate to serve as an energy substrate.
When neurons are active, nearby support cells produce lactate from sugar, which gets sent to neurons. Inside neurons, lactate is turned into pyruvate by a specific enzyme in the mitochondria. This pyruvate then fuels the cell's energy factory to make ATP. Without this conversion, neurons cannot make energy even if sugar is present. The same process also produces a molecule that neutralizes harmful chemicals formed during activity, protecting neurons from damage.
What the research says
1 studyWhen scientists blocked the enzyme that turns lactate into pyruvate in rat brain slices, the neurons stopped working—even when glucose was around. This proves lactate has to be changed into pyruvate first to give neurons energy.
