2 mechanisms by which ATP is made & the metabolic pathways that use them. |
1. Substrate level phosphorylation (occurs during krebs cycle & gycolysis) 2. Oxidative phosphorylation (occurs in ETC) Cellular respiration is the metabolic pathway utilized by this mechanism |
|
|
What are the roles of enzymes? |
To act as a catalyst to increase the rate of all the chemical reactions within cells |
|
|
3 Steps in cellular respiration |
1. Synthesis of Acetyl-CoA 2. Krebs cycle 3. ETC |
|
|
3 stages of gycolysis |
1. Energy investment stage 2. Lysis stage 3. Energy conserving stage |
|
|
6 stages of citric acid cycle |
1. Anabolism 2. Isomerization 3. Redox reaction 4. Decarboxylation 5. Substrate level phosphorylation 6. Hydration |
|
|
4 Stages of ETC |
1. e- move down the chain 2. Their energy is used to pump H+ protons across the membrane 3. The protons then flow through ATP synthase, phosphorylating ADP to make ATP 4. 1 molecule of ATP is generated for every 2 protons that cross the membrane |
|
|
2 types of fermentation |
1. Phenol acid fermentation 2. Lactic acid fermentation |
|
