Energy Transfer
Demonstration
 Elicit
 Is there energy in food?
 When burning a food item how
much change in water temperature
will there be?
 Discuss
16
Cellular Respiration
3D MODEL
 Explore
 Construct models to represent the
reactants in the equation of
cellular respiration.
 What is the equation for cellular
respiration?

17
Cellular Respiration
3D MODEL
 Explore
 Disassemble the reactants and
create the products of cellular
respiration.
 What did you notice about the
number of atoms in the products
as compared to the reactants?
19
Cellular Respiration
3D MODEL
 Explain
 Discuss “Conservation of Matter”
 Magnetic Concept Map
 Connect respiration to the reactions
of photosynthesis.
 Relate this to the Carbon Cycle.

Mitochondrion
 Outer Membrane-layer of phospholipids
 Inner Membrane-more permeable than outer
membrane
 Intermembrane space-between the outer and
inner membranes
 Cristae-layers of inner membrane folds that
increase surface area.
 Matrix-site of Kreb’s cycle
 Ribosome-site of protein synthesis
 mDNA-DNA found only in mitochondria
25
 ATP Synthase-enzyme that makes ATP from ADP
Mitochondrion
 Matrix- site of the Kreb’s cycle
 Ribosome- site of protein synthesis
 mDNA- DNA found only in mitochondria
 ATP Synthase- enzyme that catalyzes
phosphorylation of ADP to ATP.
26
Mitochondrion
 Explore
 Construct a mitochondrion model
 Explain
 Describe the function and
structure of a mitochondrion
27
Chloroplast
Intergrana
28
Structure of a Chloroplast
Membrane - Layers of phospholipids
Thylakoid - Flattened interconnected sacs that
are stacked like coins
Granum
- The name given to each stack of
thylakoids.
Intergranum - Connects the thylakoid
Lumen
- Cavity or thylakoid space
Stroma
- Fluid outside the thylakoid that
contains DNA and ribosomes
