METABOLIC PATHWAYS ANALYSIS 2026
◉ Electronegativity
Answer: an atom's attraction for the electrons in a covalent bond
-more electronegative, the more strongly it pulls e- to itself
◉ nonpolar covalent bond
Answer: the atoms share the electron equally
◉ polar covalent bond
Answer: -one atom is more electronegative (greater affinity), and the
atoms do not share the electron equally
-causes a partial positive or negative charge
◉ Water in terms of charges & electronegativity
Answer: -oxygen= more electronegative therefore partially negative
-hydrogens=partially positive
, ◉ inonic bond
Answer: -ion when an atom gains or loses one or more e-
- atoms either donate or recieve e-
-involve the electrical attraction btwn atoms (opposite charges are
attracted)
-break down easily in water
◉ Cation
Answer: A positively charged ion
◉ Anion
Answer: A negatively charged ion
◉ Which are weak chemical bonds?
Answer: ionic & hydrogen
reinforce shapes of large molecules & help molecules adhere to each
other
◉ Hydrogen Bonds
Answer: -forms when a hydrogen atom covalently bonded to one
electronegative atom is also attrached to another electronegative
atom
