Unit 4: Energy Flow ATP, Photosynthesis, and Cellular Respiration
The NADP+ then becomes NADPH
Review of the light reaction
This takes place in the stroma
The dark reaction AKA the Calvin Cycle
photosynthesis is a biochemical pathway
that takes place throughout the chloroplast
photosynthesis occurs in plant cells ....
To sum up....
Just like the chloroplast, space is maximized by having a convoluted inner membrane - the Cristae
Just like photosynthesis, respiration is a series of biochemical pathways that take place in different parts of the organelle.
However, a difference is the first part of respiration takes
place in the cytoplasm
anaerobic vs aerobic
Occurs in the matrix.
Uses pyruvic acid as a raw material
Produces: 2 ATP, 6NADH & 2FADH2
Waste product is carbon dioxide.
The Krebs cycle: in the mitochondria
Energy is stored in the bonds between the 2nd and 3rd phosphate in ATP
when the cell needs energy it breaks that bond to create ADP
ATP the currency of the cell
Endothermic - absorbs heat, H > 0
Exothermic - releases heat,H
Endergonic - NON-SPONTANEOUS, G > 0
Exergonic - SPONTANEOUS, G
Prokaryotes rely on anaerobic respiration - without oxygen
Anaerobic respiration/ glycolysis takes place in the cytoplasm of ALL cells.
Energy Flow: Photosynthesis and Cellular Respiration PPT
Photosynthesis is the first stage of energy flow through an ecosystem. You and all other animals on earth rely on the energy that plants store for life. But animals aren’t the only organisms that burn energy. Plants burn energy as they grow, too. In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.

Plants make their own food by photosynthesis. Carbon dioxide and water react together in the presence of light and chlorophyll to make glucose and oxygen. The glucose is converted into starch, fats and oils for storage. It is used to make cellulose for cell walls, and proteins for growth and repair. It is also used by the plant to release energy by respiration.
What Are Photosynthesis and Respiration? - dummies
It is then converted to thermal energy.
From all of the thermal energy produced from the hydrosphere and lithosphere from absorbing the radiant energy from the sun, only 0.023% is directly absorbed by organisms through photosynthesis and then turned into chemical energy.
The process by which the sun energy is turned into chemical energy
Carbon dioxide + Water Sugar + Oxygen
