These flashcards explain key concepts related to oxygen use during and after exercise, including EPOC (Excess Post-exercise Oxygen Consumption), oxygen deficit, and the two stages of recovery. They highlight how the body restores itself to a pre-exercise state and compensates for oxygen demands during physical activity.

What are the two ways a cell can reproduce?
Mitosis and Meiosis
Is the cell an exact copy of parent cell in mitosis?
Yes
Is the cell an exact copy of parent cell in meiosis?
No
When does meiosis happen?
In reproductive cells called gametes
What kind of cell controls differentiation?
Zygotes
What is gastrulation?
Early process of embryotic cell development of most animals.
Name the three layers developed during gastrulation
Ectoderm, mesoderm, endoderm.
Where does the nervous system develop from?
Ectoderm
Where does the muscular system develop from?
mesoderm
Where does the digestive system develop from?
endoderm
Name the 6 steps in mitosis in order
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
What happens in interphase?
The cell prepares for division by replicating genetic material
What happens during prophase?
Chromatin thickens to develop nuclear membrane, Centrioles move to OPPOSITE sides of cell, Mitotic spindle moves chromosomes around in cell
What happens during metaphase?
Mitotic spindle moves to the center, and chromosomes align along the center spindle.
What happens during anaphase?
Pairs of chromosomes (sisters), begin to pull apart, Grooves appear in cell membrane
What happens during Telophase?
Spindle deteriorates, nuclear membrane forms, chromosomes revert to chromatin.
What happens in cytokinesis?
Physical splitting of the cell.
