How many membranes enclose the mitochondrion?
Describe the endosymbiotic hypothesis on the origin of
Chloroplasts and Mitochondria
Chloroplasts are divided into three major compartments
by internal membranes:
What is central to the
processes that make energy available to the cell
Endosymbiotic hypothesis
Evidence for endosymbiosis
The ingredients for photosynthesis are
Cellular Respiration
The Relationship between Cellular
Respiration and Breathing
Where does cellular respiration occur?
Equation for cellular respiration
Redox Reactions
(Oxydation Reduction Reactions)
Redox reaction
Why does electron transfer to
oxygen release energy?
Metabolism has two parts:
3 stages of cellular respiration
NADH and Electron Transport Chains (ETC)
Stage 1: Glycolysis
Glycolysis makes some ATP directly when ....
What are the net molecular products of
Glycolysis, for each glucose molecule used?
Glycolysis Summary
Stage 2: The Citric Acid Cycle
(TCA cycle or Kreb Cycle , Hans Krebs: 1930)
Grooming of Pyruvic Acid to Enter Mitochondria
Stage 3: Electron Transport Chain (ETC)
Oxidative Phosphorylation
Mitochondrial Electron Transport Chain
Oxidative Phosphorylation
When the hydrogen ions flow back by facillitated
diffusion through the membrane, they release
Cellular respiration can “burn” other kinds
of molecules besides glucose:
Fermentation:
Evolution Connection: The Oxygen Revolution
Almost all plants are photosynthetic autotrophs,
as are some bacteria and protists (algae)
Chloroplasts: Sites of Photosynthesis
The Overall Equation for Photosynthesis
Photosynthesis is composed of two processes:
