Lab 5 Results Flashcards
what process take place in the cytoplasm of the cell
glycolysis and fermentation
what process take place in the mitochondria
- pyruvate processing
- oxidative phosphorylation
- citric acid cycle
what is the initial reactant in cellular respiration
glucose
what are the products of anaerobic processes
- lactic acid
- ethanol
- ATP
what was the correlation between volume of 5 hour energy and the metabolic rates of the worms
as the volume of 5 hour energy increased, the metabolic rates increased as well
what are the ingredients of the 5 hour energy drink
lots of caffeine and vitamins, but no sugar
why do the worms become more active with the addition of 5 hour energy
due to the caffeine
how many molecules of glucose does aerobic respiration start with
1 molecule
how many reactions are there in cellular respiration
10 reactions
- each one has an enzyme
how many pyruvate are given off from 1 glucose molecule
2
what is gained in aerobic respiration
- 2 ATP
- 4 ADP
how many CO2 and NADH are produced from 2 pyruvate
- 2 CO2
- 2 NADH
- -along with 2 Acetoly coe A
what molecule is needed for the citric acid cycle to happen
O2
what does the citric acid release
4 CO2 from 2 acetyl CoA
where in the mitochondria does the citric acid cycle take place?
matrix of mitochondria
what happens within the citric acid cycle
- 2 turns produce 6CO2, 4ATP, 10NADH, and 2FADH per glucose
- generates NADH and FADH2
what are the two types of fermentation
- lactic acid
- ethanol
what is the equation for ethanol
C2H5OH
where does oxidative phosphorylation occur
inner membrane of mitochondria
when and where does the substrate level phosphorylation occur
- during glycolysis
- in the citric acid cycle
what are some of the functions of substrate level phosphorylation
- synthesize ATP
what are the functions of the oxidative phosphorylation
- movement of protons
- procuring ATP based on proton gradient
- makes ATP during cellular respiration
- movement of electrons releases energy that is sued to make ATP
what includes the electron transport chain and chemiosmosis
oxidative phosphorylation
what is glycolysis
series of reactions that extract energy from glucose by splitting into 2 3 carbon molecules called pyruvates
what are the main parts of the mitochondria that deal with cellular respiration
- matrix ( pyruvate processing location)
- inner membrane
- intermembrane space
- outer membrane
- cristae (actual folds)
what occurs in the inner mitochondrial membrane
electron transport chain and oxidative phosphorylation
when is fermentation used
when something does not have enough oxygen to go through cellular respiration
how much ATP is produced from fermentation
2
what is the main fucntion of fermentation
provide an alternative pathway to recycle NAD+ from NADH
- electrons from NADH are transferred to pyruvate
how many ATP does cellular respiration make
29
