1Cells require what to perform task?
Transfer of energy from outside sources.
2What is Cellular Respiration?
Process that uses O2 as a reactant to break down organic molecules
3What is the process of making ATP?
Nonspontaneous (Anabolic/Endergonic)
4What kind of process is Fermentation?
Spontaneous (Catabolic/Exergonic)
5Name the 2 kinds of processes involved in breaking down glucose in the body?
Cellular respiration and Fermentation
6What is Fermentation?
Partial degradation of sugars in the absence of oxygen
7Define Reduction...
The addition of electrons
8What is the difference between cellular respiration and fermentation?
Cellular respiration is more efficient than fermentation.
9What do Catabolic pathways do to electrons?
Catabolic pathways relocate electrons stored in food molecules which releases energy used to synthesize ATP
10Define chemical reactions in terms of electrons
The transfer of 1 or more electrons from 1 reactant to another
11Oxidation reaction is also called...
Redox reaction
12Define Oxidation...
The loss of electrons
13In what 3 stages does respiration occur?
Glycolysis, Pyruvate oxidation/Citric acid cycle, Electron transport chain (Oxidative phosphorylation)
14What is Oxidative phosphorylation?
Process where the energy from the reduction of oxygen is harnessed and created in the form of ATP. This process produces 90% of ATP.
