In ___________, ATP production is very low and there is a buildup of lactic acid as a byproduct
Anaerobic respiration
In anaerobic respiration gluecose is broken down into _______ _________
Lactic acid
In the Nazi gas chambers, ___________ was used to cause death as this gas which blocks the enzyme that transfers hydrogen to oxygen
Hydrogen cyanide
Hydrogen cyanide inhibits ________ _________ by blocking the enzyme that transfers hydrogen to oxygen
Aerobic respiration
When you eat food, your body utilizes the ________within it to make carbon dioxide and water
glucose
In physical exercise _________ provides the chemical energy to power muscle contractions
ATP
Enzymes accelerate chemical reactions but remain _________ themselves
Unchanged
___________. are proteins that facilitate biochemical reactions
enzymes
Your body is only a temporary home for hydrogen, oxygen, and _________ atoms
carbon
The French scientist, Antoine Laviosier, developed the Law of ________ to describe the fact that matter cannot be created nor destroyed
Conservation of Matter
Compare and contrast anaerobic and aerobic respiration
aerobic and anaerobic respiration are the processes by which animals make energy from the conversion of carbohydrates into water and carbon dioxide. Aerobic respiration requires the presence of oxygen to produce ATP. Anaerobic repiration can occur in the absence of oxygen, but only produces 5% of the ATP as aerobic respiration, and can lead to the build-up of lactic acid
In ___________, ATP production is very low and there is a buildup of lactic acid as a byproduct
Anaerobic respiration
How is aerobic respiration related to photosynthesis?
Respiration and photosynthesis can be thought of as interrelated chemical processes. In photosynthesis, carbon dioxide and water are used to produce energy (carbohydrates) and oxygen. Respiration requires carhobydrates and oxygen to produce energy (stored as ATP) with the byproduct of carbon dioxide
In anaerobic respiration gluecose is broken down into _______ _________
Lactic acid
Describe the Law of Conservation of Matter. Explain how Earth can be considered a closed system and give an example from class/text which illustrate the effect of anthropogenic environmental contamination of human and animal health
The Law of Conservation of Matter states that matter is neither gain nor lost in a chemical reaction, but that elements are only rearranged with an input or release of energy.



Earth can be considered closed system as most all of the elements here are cycled, and thus man-made chemicals stay in the environment, to be utilized again and again.



In Missouri, it was discovered that men were experiencing low sperm count, which was most likely a result of the inputs of farm chemicals into the local drinking water.



Beluga whales living in the St. Lawrence Seaway were discovered to have a very high cancer rate. These cancers were linked to the interaction of the many chemicals to be found polluting this waterway. Although individually these chemicals may not cause cancer, their interaction could potentially have serious consequences to wildlife including the whales.
In the Nazi gas chambers, ___________ was used to cause death as this gas which blocks the enzyme that transfers hydrogen to oxygen
Hydrogen cyanide
What are enzymes and what are their properties?
Enzymes are proteins that have complex structures allowing them to catalyze highly specific biological reactions. Enzymes contain active sites that bind the compounds involved in the chemical reaction, substrates. Enzymes remain unchanged during the chemical reactions even thought they facilitate changes in teh substrate. An enzymes function can be affected by inhibitors which prevent the enzyme from binding the substrate normally.
Discuss 2 inhibitors of aerobic respiration. Tell how they inhibit and what is the end result to the organism
Hydrogen cyanide: Is a competitive inhibitor for one of the enzymes responsible for the transfer of hydrogen to oxygen. It kills the same way as suffocation does.
Carbon monoxcide: this exhaust gas kills by disrupting aerobic respiration. It has the ability to displace oxygen from binding to hemoglobin. It is 200x stronger affinity to hemoglobin than oxygen. It results in oxygen deprivation killing the organism.
Hydrogen cyanide inhibits ________ _________ by blocking the enzyme that transfers hydrogen to oxygen
