Document Summary

Module 25 cellular respiraion 1: digesion and glycolysis. Energy and nutrient acquisiion: transfer of chemical energy from various sources into cellular respiraion pathways. Aerobic cellular respiraion: c6h12o6 + 6o2 6co2 + 6h2o + atp + heat, glucose + oxygen carbon dioxide + Cellular respiraion controlled glucose combusion: extract energy in steps, allows energy to be used in other processes. A lot of energy in a glucose molecule. Glycolysis pyruvate oxidaion citric acid cycle oxidaive phosphorylaion. Universal, ancient pathway: all organisms use glycolysis. Glucose isn"t the only molecule for energy. Glucose (6 carbons) oxidized into 2 molecules of pyruvate (3 carbons each) Electrons removed are delivered to nad+ producing nadh. Each glucose molecule oxidized produces: 2 atp, 2 nadh, 2 pyruvate. Glycolysis breaks down glucose into pyruvate, in the cytosol. Two molecules of atp are used in the energy- investment phase.

The Major Metabolic Processes of Eukaryotic Cells

Plants are classified into a unique Kingdom based on the fact that they are able to make their own food. Some of this food is stored for later use but some of it is used immediately for various metabolic processes that require energy in the form of ATP. Considering this, imagine the inside of a plant cell where both anabolic Photosynthesis and catabolic Aerobic Cellular Respiration are occurring. In order for this plant cell to stay alive it must stay in a constant state of disequilibrium. This requires that the product of one reaction does not accumulate but becomes the reactant in the next step. Fill in the following chart that organizes the major events of these metabolic processes keeping in mind how each event leads into the next.

Metabolic Process	Event	Organelle the Event takes place within	Specific Location within Organelle (Event takes place within)	Input (Reactants)	Output (Products)	Enzyme(s) Involved (may be more than 1!)	*Goal of Event* *[product(s) that get produced & why]*
Photosynthesis	Light Reactions
Photosynthesis	Calvin Cycle
Aerobic Respiration	Glycolysis
	Transition Rx
	Krebâs Cycle
	Electron Transport Chain

List the specific type of phosphorylation responsible for ATP synthesis in each of the following Events:

Light Reactions:		Krebâs Cycle:
Glycolysis:		Electron Transport Chain:
