Step 1 of Respiration in Mammals is:

• Exhaling Oxygen

• Inhaling Oxygen

• Holding your breath
• Sneezing

Step 2 of Respiration in Mammals is:

• Absorption of carbon dioxide from the bloodstream

• Transport of oxygen to the cells in the body

• Conversion of glucose into energy in the cells
• Diffusion of oxygen into the blood cells

Step 3 of Respiration in Mammals is:

• Blood (carrying Oxygen) travels to body cells

• CO2 travels to body cells

• CO2 breathed out

• O2 is inhaled

Step 4 of Respiration in Mammals is:

• CO2 diffuses into the cell

• O2 travels to the heart

• Oxygen diffuses into the cells

• CO2 is exhaled

4. 4. Where do our bodies obtain the energy to do cellular respiration?

• Directly from oxygen

• From the energy stored in glucose

• from releasing Co2

(not on wkst) The little red "plugs" found in these two structures are called "heme" groups. They contain an iron atom that can bind oxygen. Which molecule contains more "heme" groups?
