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 ATP Synthase-enzyme that makes ATP from ADP25

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.
