respiration
| Question | Answer |
|---|---|
| first stage of respration | glycolysis in the cytosol |
| what happens in glycolysis | glucose is broken down into 2 pyruvic acid molecules,energy is released,ATP is formed from ADP+P,NADH is formed and electron and protons |
| what organelle does the carbon conataining molecule enter | mitochondrion |
| identigy the gas and other product produced by the yeast | carbon dioxide and ethanol |
| what solutuon could identify the co2 | limewater |
| whats the stage where acetyl cOA undergoes a series of reactions | citric cycle |
| what molecule carries electrons and protons to the electron transport chain | NADH |
| how does atp synthase use proton gradient to make atp | etc pumps h+ ions across membrane,creating a proton gradient,lots of h+ on onse side,h+ has to move thru atp synthase,as it moves thru energy is provided which makes adp+P=atp. |
| what conditions are equired for fermentation to occur | no oxygen and optimum temperature for Ph |
| what kingdom is yeats from | fungi |
| role of ATP in cellular reactions | energy carriers |
| waste product of fermentation when it occurs in animal cells | lactic acid |
| what is fermentation | the breakdown of glucose without oxygen to release a small amount of energy (ATP) (yeast breaks down glucose) |
| under what conditions will the 3 carbon atoms join the second stage | presence of oxygen |
| where does electron transport take place | cristae |
| what are stage 2 and 3 of repiration | 2)Krebs cycle,mitochondria matrix 3)etc,inner mitchndrial membrane. |
| explain stage 2 of the krebs cycle | takes place in the mitochondria,if oxygen is present pyruvate enters the mitochondria,loses a carbon dioxde to form acetyl coenzyme A,electron lost here are used to make NADH which enters an electon transport system where energy is produced as well as H20 |
| where might anaerobic repiration occur | in muscle cells if extreme execrise is occurring and atp cannot be formed with aerobic respiratio quick enough using anaerobic respiration |
| how many carbon atoms present in pyruvate | 3 |
| what are the structures of ATP | adenosine,ribosome,phosphate |
| NAD meaning | nicotinamide adenine dinucleotide |
| whats a immbolised enzyme | a enzyme that has been trapped in an insoluble material |
| products of aerobic respiration | ATP and co2 |
| how many carbon atoms does lactic acid the product have | 3 |
