Unit 3 - Class 1 Flashcards
Mastery
Photosynthesis and Celular Respiration Provide energy for life
True
Life Requires Energy
True
Sun:
ultimate source of energy on earth
Draw Chloroplast and Mitochondria (with flow of energy and cycling of matter)
Class 1 study guide
Breathing - 1
Supplies O2 for cellular respiration and removes CO2
Breathing - 2
Exchange of gasses (CO2 and O2) between lungs and air
Cellular Respiration -1
Use O2 from breathing, to break down food molecules and release CO2
Cellular Respiration - 2
Banks’ energy in ATP
Cellular Respiration - 3
Exergonic (energy releasing) process
Cell…
uses energy from ATP for all it’s activities
Cellular Respiration 4
Moves electrons from Glucose to Oxygen and uses some of the released energy to make ATP
Energy originally stored in Glucose
66% is released as heat 34% is stored as potential-chemicle-energy of ATP
Oxidation
Loss of Electrons
Reduction
Gain of Electrons
What’s an example of a redox reaction?
Cellular Respiration
Cellular respiration cheimcle reaction 1
Carbon loses Hydrogen atoms, Oxygen gains hydrogen atoms
Cellular Respiration Chemicle Reaction 2
C6H12O6 + 6O2 —- 6CO2 + 6H2O + ATP + Heat
Draw Electron Transport Chain (NADH oxidized to NAD+, ETC moves e- to oxygen, Energy released by ETC used to make ATP, oxygen reduced to water)
Class 1 study guide
Draw and describe Oxidation of Glucose with reduction of NAD+ to NADH
Class 1 study guide
Draw the balanced equation of cellular respiration
Class one day paket
Draw the Mitochondria and the three stages of cellular respiration
Class one Study guide
CR Stage 1
Glycosis (cytosol)
CR Stage 2
Pyruvate Oxidation and Citric Acid Cycle (matrix)
CR Stage 3
Oxidative Phosphorylation (inner membrane)
Cells Capture Energy from Electons “Falling” from organic fuels to oxygen
Glucose is oxidized - falling electrons accepted by coenzyme, NAD+ reduced to NADH NADH delivers electrons to string of electron carrier molecules. Energy released from electrons used in making of ATP At end of ETC osygen accepts 2e-, picks up 2 H+ ,reduced to water
Photosynthesis
green plants and other organisms transform light energy into chemical energy
Cellular Respiration
organisms use oxygen to break down food molecules,
getting chemical energy for cell functions
Breathing
process of respiration, air is inhaled into lungs due to muscle contraction then exhaled due to muscle relaxation.
Redox Reactions
reactions that involve the transfer of electrons from one species to another
Coenzyme
organic compounds that
facilitate action of enzymes
can bind temporarily or permanently to an enzyme
Matrix
Inside of Mitochondria
Christie
Folds in Mitochondria
NAD+/NADH
electron carriers
temporarily stores energy during cellular respiration
Cytoplasm
Ouside Cell holds internal compounds in place
Outer Membrane, Inner Membrane, Inner Membrane Space
Outside wall of mitochondria, outside wall of matrix space, space between two membranes
Glycosis
splits glucose into two pyruvate molecules
Pyruvate Oxidation
oxidation of pyruvate
creating acetyl CoA
Citric Acid Cycle
metabolic pathway connecting carbohydrate, fat, and protein
reactions carried out by eight enzymes that completely oxidize acetate
Oxidative Phosphryalation
harnessing reduction of oxygen
generating high energy phosphate bonds
Chesmiosomosis
Electron Transport Chain
movement of hydrogen ions across the membrane through ATP synthase
electrons pass from one molecule to another, energy released in electron transfers form an electrochemical gradient.
