What is the product when adding Nicotine and chromic acid?

Nicotinic acid and Chromic oxide
What is difference between nicotinic acid and nicotinamide ?

Nicotinc acid has a carboxyl group

nicotinamide has an amine group
Where does Glycolysis occur?

cytoplasm
Where does pyruvate processing and krebs cycle occur ?

mitochondria
Electron transport and oxidative phosphorylation occur?

mitochondria
(glycolysis steps) first step
- Take ATP and take its phosphate group to add it to glucose
- **it turns into Glucose 6-phosphate
- *turns ATP into ADP
- *uses energy
(glycolysis) 2nd step

Glucose 6-phosphate is rearranged into Fructose 6-phosphate
(glycolysis) 3rd step

-use another ATP

-Adds another Phosphate group to Fructose 6-phosphate and it will turn into Fructose 1,6 biphosphate
(glycolysis) 4th step

reaction occurs which splits fructose 1,6 biphosphate into 2 3-carbon sugars that are identical
(glycolysis) 5th step
- 2NAD+ is turned into NADH
- *reduced reaction
(glycolysis) 6th step
- 2 molecules of ATP are formed
- *one from each sugar molecule
(glycolysis) 7th step

goes through couple more steps till finally at second to last step, 2 ATP molecules are produced
(glycolysis) 8th step

LAstly , Pyruvate comes out
(Slide 19) Product can activate feedback inhibition

-product can turn around ad bind allosterically on the enzyme to slow or inhibit the reaction
What happens when ATP levels are very high

ATP can bing to an enzyme at a allosteric binding site to inhibit or slow down the activity of an enzyme
What happens in the initial glycolysis steps?

we waste energy
WHich has more energy ATP or NADH?

NADH
What happens if there is an electron acceptor such as oxygen?
- it goes into cell respiration
- *kreb cycle and electron transport and oxidative phosphorylation
What happens if there isnt an electron acceptor such as oxygen?

celll goes into fermentation
What molecule is the frist in kreb cycle?

citrate
which molecule is the last?

oxaloacetate
Which is strongest and weakest molecule in kreb cycle?

reduced: Citrate

oxidized: Oxaloacetate
What is matrix like?

cytoplasm
What are the membranes inside the mitochondira reffered to as by>

cristae
Where does the kreb cycle occur at?

matrix
What happens to pyruvate before going into krebbs cycle?

-rips a carbon off to produce CO2

-reaps some NAADH
What does Acetyl CoA do?

-takes acetyl group and throws it into kreb cycle

-changes oxaloacetate into citrate
Why is Coenzyme A important?

it transfer an acetyl group to oxaloacetate
(krebbs cycle) What happens when acetyl binds with oxa?
- they formed Citrate
- *6 carbon molecule
(krebbs cycyle)WHAT HAPPENS after 2nd and 3r reaction?

CO2 is ripped off
(krebbs cycle) when is glucose broken down completely?

after 3rd reaction
