Cellular energy

Photosynthesis and Cellular Respiration

This molecule is made-up of adenine, ribose, and 3 phosphate groups. ATP
This molecule is made-up of adenine, ribose, and 2 phosphate groups. ADP
Adding a phosphate group to ADP to make ATP _________ energy. stores
Removing a phosphate group from ATP to make ADP _________ energy. releases
Organisms that produce their own food are called Autotrophs or producers
Organisms that have to consume food for energy are called Heterotrophs or consumers
Found in plants, this pigment reflects green light. Chlorophyll
Molecules that absorb the sun's energy are called pigments
1st step of cellular respiration - breaks down glucose into pyruvic acid. Glycolysis
What are the reactants of cellular respiration? oxygen and glucose
What are the reactants of photosynthesis? carbon dioxide and water
What are the products of cellular respiration? carbon dioxide and water
What are the products of photosynthesis? oxygen and glucose
2nd step of cellular respiration - breaks down pyruvic acid into carbon dioxide. Kreb's Cycle
3rd step of cellular respiration - produces water and up to 34 molecules of ATP. Electron Transport Chain
Photosynthesis takes place in the chloroplast
Cellular respiration takes place in mitochondria
What lab technique did we use to separate the different pigments of a spinach leaf? paper chromatography
1st step of photosynthesis - requires light energy to split water into oxygen gas and hydrogen atoms. Light-Dependent Reaction
2nd step of photosynthesis - uses ATP as its source of energy to add hydrogen atoms to carbon dioxide and make glucose. Calvin Cycle
The initial source of energy for most communities is sunlight.
The energy released from ATP breaking down into ADP is used to perform cellular work & life functions.
Special protein used in Electron Transport Chain that spins as hydrogen ions move through it. The spinning motion provides energy to make ATP molecules. ATP Synthase
Amount of energy that can be passed on from one trophic level to the next. 10%
Organisms that break down organic matter and return nutrients to the environment. decomposers
Organisms that feed on (consume) dead or decaying matter. detritivores
Anaerobic process that harvests energy from food to make ATP. fermentation
Type of fermentation that produces lactic acid. lactic acid fermentation
Type of fermentation that produces ethyl alcohol and carbon dioxide. alcoholic fermentation
Type of organism that requires oxygen to survive. obligate aerobe
Type of organism that requires an oxygen-free environment to survive (is poisoned by oxygen). obligate anaerobe
Type of organism that can survive by doing either cellular respiration or fermentation. facultative anaerobe
