Cards

Term
What are organic compounds?
Definition
carbon compounds that are the building blocks and energy stores for all of life
Term
What is an autotroph?
Definition
an organism that is self nourishing
Term
How does an autotroph obtain energy?
Definition
from the sunlight
Term
Where do autotrophs get their Carbon from?
Definition
from CO2 that is in the air
Term
What is a heterotroph?
Definition
an organism that is nourished by consuming autotrophs/other heterotrophs
Term
Where does a Heterotroph obtain its carbon from?
Definition
organic compounds put together by other organisms
Term
What is an ATP?
Definition
the unit of energy that is used by cell
Term
What is ATP coverted from?
Definition
sugar molecule
Term
What is photosynthesis?
Definition
the converting of energy from the sun into chemical energy needed by plants
Term
Where does photosynthesis occur?
Definition
in the chloroplasts
Term
What is the main catalyst in photosynthesis?
Definition
chlorophyll
Term
How does oxygen and CO2 enter and leave the cell?
Definition
through tiny openings in the leaves called stomata
Term
What is the formula for photosynthesis?
Definition
[image]
Term
What are the 2 stages of photosynthesis?
Definition
Light dependent stage & Light independent stage
Term
What is the light dependent stage?
Definition
the stage where ATP is produced
Term
What is the Light independent stage?
Definition
the stage where glucose is produced and converted into sugars, starches, and cellulose from ATPs
Term
What are photons?
Definition
distinct packages in which light travels. These are absorbed by pigments in plants.
Term
Why do photosynthetic reactions vary?
Definition
light intensity available varies, air temperature varies, amount of rainfall varies, soil types vary
Term
Explain Engelmann's Experiment.[image]
Definition
The bacteria grows in the Blue and Red light spectrums because the algae gives off oxygen because they carry out photosynthesis using the blue and spectrums.  This experiment shows that green plants absorb red and blue light and reflect green light.
Term
What is a C4 pathway plant?
Definition
plant that partially closes its stomata during hot days and fixes its CO2 onto 4-carbon molecules
Term
What is a CAM pathway plant?
Definition
plant that opens their stomata at night and close them during the day like cactus and pineapples. carbon dioxide is fixed to special organic molecules during the night and released during the day
Term
What is cellular Respiration?
Definition
the process of breaking down food substance into usable energy like ATP
Term
What are the 2 types of cellular respiration?
Definition
aerobic and anaerobic
Term
What is the 1st stage in all cellular respiration?
Definition
glycolysis
Term
Where does glycolysis take place?
Definition
cytoplasm
Term
what 3 things come from glycolysis?
Definition
2 ATP, NADH, and pyruvate
Term
What is the 2nd stage of aerobic respiration if there is oxygen?
Definition
the Citric Acid Cycle
Term
What is the 3rd thing in cellular respiration with oxygen?
Definition
ETP-Electron transport phosphorylation
Term
What is the formula for aerobic respiration?
Definition

[image]

PLEASE NOTE THAT IT IS SUPPOSED TO BE 36 ATP NOT 38

Term
What are the 2 types of anaerobic respiration?
Definition
Lactate(lactic acid) Fermentation and alcohol fermentation
Term
Why does anaerobic respiration happen?
Definition
there is no oxygen to continue cellular respiration
Term
What kind of fermentation do muscles(excluding the brain) use?
Definition
Lactic acid fermentation
Term
What is the formula for anaerobic respiration?
Definition
C6H12O6-------> 2ATP + alcohol/lactic acid
Term
Where does the citric acid cycle and ETP occur?
Definition
the mitochondria
Term
What does the body do if there is not enough glucose?
Definition
releases energy stored as glycogen, proteins, and fats
Term
What does the body do if there is too much glucose?
Definition
store it as glycogen, fat, and proteins
Term
Where is glycogen stored?
Definition
in the liver
Term
When food is digested, what 3 things are produced?
Definition
fats, complex carbohydrates, and proteins
Term
What are complex carbohydrates broken down into?
Definition
simple sugars
Term
What process do simple sugars enter into?
Definition
glycolysis
Term
What are fats broken down into?
Definition
fatty acids and glyceroll
Term
What is extra sugar turned into after it enters glycolysis?
Definition
glycogen
Term
What thing from fats enter into glycolysis?
Definition
glyceroll
Term
What are proteins broken down into?
Definition
amino acids
Term
What 2 things come from amino acids?
Definition
carbon backbones and urea
Term
How many ATP are produced in the Citric Acid Cycle?
Definition
2 ATP
Term
What else is produced/released in the citric acid cycle?
Definition
carbon dioxide
Term
What 3 things enter into ETP?
Definition
NADH, FADH2, and O2
Term
What 2 things are produced in ETP?
Definition
32 ATP and water
