Anaphase
A Stage Of Mitosis In Which Sister Chromatids Separate And Move Toward Opposite Poles.

Metaphase
A Stage Of Mitosis In Which Chromosomes Align At The Cell Equator Before Being Separated.

Prophase
The First Stage Of Mitosis In Which Chromosomes Condense And The Nuclear Envelope Begins To Break Down.

Interphase
The Longest Phase Of The Cell Cycle In Which The Cell Grows, Replicates Dna, And Prepares For Mitosis.

Cell Cycle
A Repeating Sequence Of Growth And Cell Division In Eukaryotic Cells, Including Interphase And M Phase.

Feedback Inhibition
A Regulatory Mechanism In Which The End Product Of A Metabolic Pathway Inhibits An Earlier Enzyme In The Pathway.

Metabolic Pathway
A Series Of Linked Chemical Reactions In An Organism, Often Regulated By Multiple Enzymes.

Activation Energy
The Minimum Amount Of Energy Required For A Chemical Reaction To Begin, Often Lowered By Enzymes.

Denaturation
A Structural Change In A Protein Such As An Enzyme Caused By Heat, pH, Or Chemicals, Resulting In Loss Of Function.

Active Site
The Region On An Enzyme Where The Substrate Binds And The Chemical Reaction Occurs.
