Chapter 8a - Cell Energy Flashcards
The ability to do work
Energy
The study of the flow and transformation of energy in the universe
Thermodynamics
All the chemical reactions in a cell
Metabolism
Two-phase anabolic pathway in which the sun’s light energy is converted to chemical energy for use by the cell
Photosynthesis
Catabolic pathway in which organic molecules are broken down to release energy for use by the cell
Cellular Respiration
Energy-carrying biological molecule, which, when broken down, drives cellular activities.
Adenosine triphosphate (ATP)
In chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light-dependent reactions occur
Thylakoid
One of the stacks of pigment-containing thylakoids in a plants chloroplasts
Granum
Fluid-filled space outside the grana in which light-dependent reactions take place
Stroma
Light-absorbing colored molecule, such as chlorophyll and carotenoid, in the thylakoid membranes of chloroplasts
Pigment
In photosynthesis, the major electron carrier involved in electron transport
NADP+
Light-independent reactions during phase-2 of photosynthesis in which energy is stored in organic molecules as glucose
Calvin Cycle
Enzyme that converts inorganic carbon dioxide into organic molecules during the final step of the Calvin Cycle
Rubisco
