how nutrients generally move among organisms, origin of mineral N: Atmospheric N₂ is converted into mineral forms (NH₄⁺, NO₃⁻) by: Biological fixation (by bacteria in roots or soil) Lightning fixation Industrial fixation (fertilizers); N cycling: i. Plant uptake and incorporation (mineral → organic N) ii. Resorption before leaf fall (retranslocating nutrients) iii. Decomposition of litterfall (organic → mineral N)

importance of nutrient resorption: Plants withdraw nutrients (like

Distribution layers: Div up to Accum + Current E&P then basis then rest equals capital gain

- No dividend if no E&P and reduce current E&P first; negative AEP still distribute E&P

- Half of current E&P lost offset AEP before distribution

Property Distribution: recognize gain but not loss

- Div = FMV - liabilities   Basis = FMV   Gains=FMV - Tax Basis

Distribution table: (Period distribution/Total distribution)*CEP= amount from CEP; AEP = remain then stock basis

CHAPTER 4 OVERVIEW – Protein Structure & Function

Proteins are at the center of all biological processes.
They catalyze reactions, regulate pathways, transport molecules, and form most of the structural framework of cells.

Core Principle: Structure → Function.

Key Historical Milestones:

  • Hsien Wu (1931): showed that denaturation destroys non-covalent interactions → unfolding = loss of function.
  • Bernal & Hodgkin (1934): X-ray diffraction of pepsin → proteins are ordered, crystalline
