Photosynthesis + Cellular Respiration Flashcards
What is photosynthesis?
The process that plants use to make their own food/energy
What is an autotroph?
An organism that can make its own food for energy
What is a heterotroph?
An organism that has to eat food to get energy (they can’t make their own food)
What is cellular respiration?
The process that plants and animals use to get energy from food
How many steps are in cellular respiration?
3 - Glycolysis, the Kreb’s Cycle, and the electron transport chain
True or false: only plants do cellular respiration
False - animals do it too
What is pigment?
Substance that gives color to plant or animal tissue
What does pigment do in photosynthesis?
It captures light energy and converts it to chemical energy
What is chlorophyll?
A pigment that plants use to make food during photosynthesis
What is the electron transport chain?
A series of protein complexes that facilitates the transfer of electrons from NADH and FADH2 to molecular oxygen
What is carbon dioxide fixation?
A step in the Calvin cycle in which inorganic carbon is converted into organic compounds
Where does carbon dioxide fixation occur?
In the stroma of chloroplasts
What is aerobic respiration?
Producing energy with oxygen (a lot of ATP, like 36-38)
What is anaerobic respiration?
Producing energy without oxygen
What is glycolysis?
The first step in cellular respiration which is a set of reactions that converts glucose to pyruvate or lactate
Fermentation
An anaerobic metabolic process where micro organisms break down carbohydrates into products
What is stomata?
Tiny pores on plant leaves and stems that facilitates gas exchange between the plant and its environment
What is the stroma?
A fluid filled space in chloroplasts where the Calvin cycle takes place
What is the Calvin cycle?
A series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose during photosynthesis
What is the Kreb’s Cycle?
A series of chemical reactions that break down food molecules to release ATP, NADH, and FADH2
