Categories of metabolism Catabolic Process & Anabolic Process Process that releases energy Catabolic Process Process that requires input of energy Anabolic Process Type of metabolism that starts with high energy materials? Catabolic Metabolism Type of metabolism that starts with low energy materials? Anabolic Metabolism Endergonic Absorbing energy in the form of work. Not spontaneous. Positive delta G Exergonic Releasing energy in the form of work. Negative delta G How can cells carry out processes that are thermodynamic endergonic? Endergonic reactions can be coupled with exergonic reactions Cells use this as an "energy current" ATP Will a hypertonic cell look either swollen or like a biconcave disk? Crenate or Hemolyzed? Swollen & Hemolyzed Are crenate cells hypotonic or isotonic? Hypotonic
