6590183770 | glycolysis | the decomposition (lysis) of *glucose* (glyco) to *pyruvate* (or *pyruvate acid*) 1 glucose → 2 pyruvate, 2 NADH, and 2 net ATP molecules | ![]() | 8 |
6590183771 | NADH | a *coenzyme* that is an electron carrier when NAD⁺ combines with 2 energy rich e⁻ and H⁺ | 9 | |
6590183772 | Krebs Cycle/CAC Citric Acid | ∙details what happens to pyruvate, the end product of glycolysis -Occurs 2x since there are 2 pyruvate molecules formed by glycolysis -Produced (after 2 cycles): 6 NADH, 2 FADH₂, 2 ATP, 4 CO₂ | ![]() | 10 |
6590183773 | oxidative phosphorylation | ∙process of producing ATP from NADH & FADH₂. that pass along the electron transport chain | ![]() | 11 |
6590183774 | electron transport chain def+pic | ∙consists of proteins that pass the electrons from NADH and FADH₂ from one carrier protein (i.e. *cytochromes*) to the next ∙Final e⁻ acceptor is *oxygen* | ![]() | 12 |
6590183775 | cytochrome C | ∙a carrier protein which is so common among living organisms that its amino acid sequence is compared among species to assess genetic relatedness | 13 | |
6590183776 | mitochondria | ∙cellular respiration takes place ∙inner membrane ∙matrix | ![]() | 14 |
6590183777 | inner membrane | ∙double phospholipid bilayer, has convolutions called *cristae* ∙oxidative phosphorylation occurs here ∙ETC removes e⁻ from NADH & FADH₂ and transports H⁺ ions from the patrix to intermediate space | ![]() | 15 |
6590183778 | matrix | ∙fluid material that fills the area inside the inner membrane. ∙Krebs cycle and conversion of pyruvate to acetyl CoA occur here | 16 | |
6590183779 | ATP synthase | ∙a channel protein in the inner membrane, allows protons in the intermembrane compartment to flow back into the matrix to generate ATP | ![]() | 17 |
6590183780 | chemiosmosis | ATP generation that occurs when energy is stored in the form of a *proton concentrating gradient* across a membrane using ATP synthase | ![]() | 18 |
6590183781 | 30-32 | How many ATP molecules does cellular respiration produced? Write as __ -__ | 19 | |
6590183782 | alcohol fermentation | ∙pyruvate to acetaldehyde to ethanol ∙occurs in: plans, fungi (yeast), and bacteria | ![]() | 20 |
6590183783 | anaerobic respiration objective | ∙replenish NAD⁺ so that glycolysis can proceed once again because in the absence of O₂, all the NAD⁺ is bottled up in NADH because oxidative phosphorylation cannot accept the e⁻ of NADH without oxygen. | 21 | |
6590183784 | lactic acid fermentation | ∙A pyruvate is converted to lactate (or lactic acid); in the process, NADH gives up its e⁻ to from NAD⁺ | ![]() | 22 |
