Respiration /Respiratory System LE Biology Unit 9
The release of energy to body cells Respiration – Overall Reaction: The exchange of gasses is needed! The release of energy to body cells Carbon dioxide + ATP Glucose Oxygen Water Respiratory Enzymes Respiratory Enzymes C6H12O6 6O2 6H2O 6CO2 + 36 ATP
Respiratory Systems of simpler organisms: 1. Monera, Protists, Fungi – Exchange of gases occurs through cell membranes. ( ) All or most of the cells are in direct contact w/ environment Thin Moist DIFUSUON
2. Plants - Through Leaves – cell membranes of internal cells surrounded by intercellular spaces of the spongy layer, ( ), Stems ( ), Roots – ( ) Diffusion Stomates Lenticels Root Hairs
3. Hydra - layers of cells/Exchange happens by the process of . 2 DIFFUSION
The presence of in the blood increases its ability to carry . 4. Earthworm – Gas exchange occurs through the . This is because of the secretion of mucus. The skin has many capillaries, so the blood passes through and picks up and gets rid of . The presence of in the blood increases its ability to carry . Thin, Moist, Skin Oxygen Carbon Dioxide hemoglobin Oxygen
5. Grasshopper – Respiratory gasses are NOT carried by the blood 5. Grasshopper – Respiratory gasses are NOT carried by the blood. They are carried by _______________________ that open to the environment through small holes in the exoskeleton on the abdomen called ________. The tracheal tubes end at _____, ______ air sacs that help to pump air through the tubs and were gas exchange occurs. Tracheal Tubes ( Tracheae) Spiracles Thin Moist
6. Frog – has _______, but not as developed as ours 6. Frog – has _______, but not as developed as ours. It exchanges gasses through its ______, ______ skin. Lungs Thin Moist
