Cellular Respiration & Photosynthesis Flashcards
What organisms use photosynthesis?
Photosynthesis is carried out by green plants, green algae, and certain bacteria.
Why are these organisms able to carry out photosynthesis?
They are able to carry out this process because of organelles called chloroplasts that contain chlorophyll.
What happens in the chloroplast organelles?
CO2, water, and sunlight or energy from the Sun produce adenine triphosphate (ATP), which is a cellular fuel that provides the energy to produce glucose from CO2 and water, liberating oxygen.
What is an autotroph?
Organisms that are able to produce food on their own and often use the process of photosynthesis.
Chemical Equation for Photosynthesis
6CO2 + 6H2O + Energy ⇒ C6H12O6 + 6O2
Carbon Dioxide + Water + Sunlight ⇒ Glucose + Oxygen
Cellular Respiration
In contrast to photosynthesis, this process uses the product of photosynthesis; glucose – to produce ATP for cells.
What type of organisms use cellular respiration?
Heterotrophs
What are Heterotrophs?
Heterotrophs are organisms that cannot produce their own food.
During cellular respiration, glucose is broken down by the process of _____________ .
Glycolysis
How does glycolysis work?
Glycolysis transfers some of the energy of glucose into ATP, which then goes through the Kreb’s Cycle.
Cellular Respiration = Glycolysis + Kreb’s Cycle
Kreb’s Cycle AKA
Citric Acid Cycle
What happens to water, carbon dioxide and oxygen during cellular respiration?
During cellular respiration, oxygen is completely used up while water and carbon dioxide result as by-products.
Chemical Equation for Cellular Respiration
C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O + Energy
List the four main stages of cellular respiration and the cellular location of each phase
Glycolysis -> cytosol
Acetyl CoA Formation -> mitochondria
Kreb’s Cycle -> mitochondria
Electron Transport Chain -> mitochondria
