Cellular respiration

Cellular Respiration

Who? Why? Where? What?



Plants and animals

  • Plants - Autotrophs:

    • self-producers.

  • Animals - Heterotrophs:

    • consumers.

Plants and Animals…



WHY?


Why cont

WHY? (cont.)


Why cont1

C6H12O6 + 6O2 6CO2 + 6H2O + energy

(Glucose) (ATP)

WHY? (cont.)



Where

  • Cellular Respiration occurs in the… monomers.

    • Cytoplasm

      • Glycolysis---Cytosol (Cytoplasm)

    • Mitochondria

      • Krebs Cycle—Mitochondrial Matrix

WHERE? (cont.)



  • Cellular Respiration: monomers.

    • catabolic, exergonic, oxygen (O2)requiring process that uses energyto extract energy (ATP) from macromolecules (glucose).

      • Catabolic: Rxn that breaks molecules down

      • Makes CO2 and H2O as well as energy (ATP)

C6H12O6 + 6O2 6CO2 + 6H2O + energy

(Glucose) (ATP)

WHAT?


Amp adp atp

  • Adenosine Tri- monomers.Phospate:

    • Made of three things

      • 1.) Ribose (sugar)

      • 2.) Adenosine (base)

      • 3.) Three phosphates

        • Key to the activity of ATP

AMP, ADP, ATP


Amp adp atp1

  • ATP works by losing the endmost phosphate group when instructed to do so by an enzyme.

  • As the molecule goes from ATP to ADP to AMP it loses a phosphate.

    • With each lost phosphate more energy is released

  • This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc

AMP, ADP, ATP


Atp to adp to adp releases energy

ATP instructed to do so by an enzyme.

Tuesday december 18 th 2012

  • QU: instructed to do so by an enzyme. How is energy released from the ATP?

    *CR Project Due Weds. at the end of the hour*

  • OBJ: C.R. Notes and C.R. Project

    “The warmest temperature ever recorded on Antarctica was 3 degrees F.”

Tuesday December 18th 2012


What cont

  • Cellular Respiration is broken into three main parts. instructed to do so by an enzyme.

    • 1.) Glycolysis: splits sugar (glucose)

    • 2.) Krebs Cycle (Citric Acid Cycle): Extracts the energy from glucose

    • 3.) Electron Transport Chain/ATP Synthase: Turns the energy into ATP for the body to use

      **In total makes 38 ATP**

WHAT? (cont.)


Glycolysis

  • Occurs in the instructed to do so by an enzyme. cytoplasm just outside of mitochondria.

  • Two phases:

    A. Energy investment phase

    -Put energy in

    B. Energy yielding phase

    -Get energy out

Glycolysis


Glycolysis step 1

    2 - NADH

Glycolysis: The final picture


The in between

  • The 2 instructed to do so by an enzyme. Pyruvates (PYR) (3 Carbons) lose one carbon each.

  • Now they each have only 2 carbons and are called Acetyl CoA

Krebs cycle citric acid cycle

Mitochondrial instructed to do so by an enzyme.

Matrix

  • Location: Mitochondrial Matrix

  • Acetyl CoA (2C)bonds to Oxalacetic acid (4C - OAA)to make Citrate (6C).

  • It takes 2 turnsof the krebs cycle to oxidize1 glucosemolecule.

    • Oxidize: remove electrons for energy

Krebs Cycle (Citric Acid Cycle)


Krebs cycle citric acid cycle1

  • Total net yield instructed to do so by an enzyme. (2 turnsof krebs cycle)

    1.2 - ATP (substrate-level phosphorylation)

    -Substrate-level phosphorylation: when phosphates are added directly to a molecule of ADP or AMP to make ATP

    2. 6 – NADH

    3. 2 - FADH2
