New cards

What do fats glucose and proteins use for energy

ATp

New cards

How do amino acids (from proteins), fatty acids (from lipids) and sugars (form polysaccarids) get into the the kreb cycle

through the Acetyl-CoA hub or amino acids can get straight to the krebs cycle

How does the Kreb cycle make H+ and e- for ETC?

  1. Acetic Acid turns into Acetate by deattaching a H

  2. a Acetyl group is attached to coA

  3. There is a sulfate group (SH) at the end of Acetyl-coA and the H goes away

  4. the sulfer attaches to a carbon and it allows the coenzyme to carry anything

All of these thing can donate high energy electrons

What are these two compounds

Acetic acid becoming acetate by deattaching a H

How can acetyl be yelid for the kreb cycle

sugars, fats and some amino acids all can be broken down to yeild acetyl forn the krab cycle in the Acetyl Co A

Where does the kreb cycle take place

inside the matrix in the mitochondria

New cards

Kreb Cycle

is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins

-circular metabolic pathway.

-It has no beginning and no end.

10
New cards

what feeds the ETC

oxygen, ATP leaves the mitochondria in all directions

11
New cards

what are the inputs and outputs of the kreb cycle

Main inputs are acetic acid and water

outputs are carbon dioxide. high energy electrons, protons and some atp on the side

12
New cards

Why is the kreb cycle also called the citric acid cycle

because it contains Citrate molecule

13
New cards

what are the molecular outputs during the kreb cycle

3 NADH, 2 CO2, ATP, FADH2

-ATP comes out of step 5 cus its more effient that way

<p>3 NADH, 2 CO2, ATP, FADH2</p><p>-ATP comes out of step 5 cus its more effient that way </p>
14
New cards

why is the krebs cycle also called tricarboxylic acid cycle (TCA cycle).

because there are tricarboxylics within the process

Singifigant events for Glycolysis

Goes from 6 carbons to 3 carbons

1.glucose gets phosporlated

  1. become furcose with 2 phosphates while using ATP

  2. eventually becomes pyruvate

    • will get a NADH out of it

16
New cards
<p>what is this compound </p>

what is this compound

pyruvate

17
New cards

what role does pyruvate play in for the kreb cycle

pyruvate contains 2 ATP for the mitochandria and enters kreb by generating a NADH anf go into the Acety-coA hub

18
New cards

mitochondrial pyruvate carriers protein funtion

pulls pyruvate in and where CO2 comes out

19
New cards

Beta oxidation

breaking up fatty acuds and how fatty acids got into kreb through Acetyl CoA

<p>breaking up fatty acuds and how fatty acids got into kreb through Acetyl CoA</p>
20
New cards

How does Beta oxidative work

  1. all kinds of fatty acids are different in length

  2. if not to long, it can go through the membrane

  3. then it takes acdric acids to the matrix

21
New cards

where do long carbons go

to prysomes, to break down the fatty acid and send them to the mitochondria

  • how mostly everything is metabolised

22
New cards

what are two ways ATP are made

  1. oxidative phoralation

  2. substarte level phorylation

23
New cards

substarte level phorylation

where a phosphate bonds to an ADP from the reactant and the product becomes a new molecule and ATP
