Reminders:
• Quiz 2 (covers Lectures 5-7)
• Oct 3 – CRN 40051
• Oct 4 – CRN 40050
• Must be completed in class – bring your
laptops
Objectives:
• Introduction to Metabolism
• Enzymes
BIOL1010 and 1
BIOL1011
, Cells Need Energy!
• Cells must harness energy
from the environment and
convert it to a form that
allows them to do work
– Synthesizing DNA, RNA, and
proteins
– Moving vesicles in a cell
– Pumping substances across
membranes
• Cells use ATP for energy
– ATP contains energy in its
chemical bonds
BIOL1010 and 2
BIOL1011
, Metabolism Overview
• Important to consider a cell’s sources of
carbon because:
– Carbon is fundamental in organic molecules
in cells
– Carbon-based compounds are a stable
energy storage form
• Organisms have two ways of harvesting
energy from their environment and two
sources of carbon…
