Photosynthesis and Cellular repiration Flashcards
What is cellular energy/ energy supplies to cellular respiration called?
ATP
What is the structure of ATP
Adenosine(2 rings of Adenine and Ribose) And triphosphate
Where does the chemical energy to produce ATP come from?
Breaking macromolecules from food, Hydrolysis
How is energy released from ATP
Breaking between 2&3 phosphate
What is the source of eneergy for chemosynthesis
Chemicals, hydrothermal vents
Define Photosynthesis
The process that produces sugas that store chemical energy, and captures the energy from the sunlight to make sugars.
What is the equation for photosynthesis
6 Carbon dioxide(6CO2)+ 6 water(H2O) tooo Glucose (C6H12O6) + 6 oxygen (O2)
What four things determine the rate of photsynthesis
Temperature, sunlight, Carbon Dioxide, and Water
What are the things that absorb colors called?
Pigments
What wave lengths of light does chloropyll absorb? Refelect?
Absorb: Red and Blue
Reflect: Green
What is a light dependent reaction?
What is a light independent reaction?
Light dependent: Captures energy from sunglught
Light Independent: Makes food
What goes in/ is used and what is made/ goes out in Light dependent reaction?
Goes in- Sunlight, Water
Made- Oxygen ATP and NADPH
What goes in/ is used and what is made/ goes out in Light independent reaction?
Goes in- Oxygen, ATP, NADPH
Made- Glucose
Where does the light dependent reaction take place?
Tykloid Membrane
Where does the Light independent reaction take place?
Stroma
What is the purpose of Photosystem
The absorption and transfer of light energy, which implies transfer of electrons.
Why is NADP+ important?
It is vital to create NADPH
What is the soruce of oxygen during photosynthesis?
Water
What is the purpose of the ETC
Split water H+, and tykloid diffusion,make large amounts of ATP
Where do H+ ions come from?
Water
What is ATP synthase? What does it do and how does it work?
a membrane-bound enzyme that uses the flow of protons (H+) across a membrane to drive the synthesis of ATP from ADP and phosphate
What is the function of glycolysis
Break down glucose into 2 3-carbon molecules
What is the function of Krebs cycle?
Trandfer energy to ETC
What is the function ETC
Produce a large amount of ATP
What is generated in glycosis? what is used?
Generated:2 3-carbon molecules, 2 ATP& 2 NADH
Used- Glucos & 2 ATP
What is generated in Krebs cycle? what is used?
Generated: Carbon dioxidde, 2 ATP, FADH2& NADH
Used- 2 3-Carbon Molecules
What is generated in ETC? what is used?
Generated: Water & large amounts of ATP
Used: Oxygen, FADH2, NADH from stages 1&2
How many ATP come fromm the complete breakdown of 1 glucose molecule
34-38
How is water created
Electron Transport Chain to oxygen to water
What muscles are excersized in the absence of oxygen, what is produced
Lactic acid
What is the main role of fermintation
Break glucose without oxygen, no ATP made, NAD+ recycled
What is produced durning alchohol fermintaion
Alcohol
what gas creates bubbles
Carbon dioxide
What are some examples of products created through alcoholic and lactic acid fermentation.
Lactic acid- Cheese and Yogurt
Alcoholic- Wine and Bread
Why do cells need to generate ATP
It powers most of the cells processes
How do cells use the oxygen that you inhale
They use it to make ATP from glucose.
