polysaccharide that is used for structural support in plants
Cellulose
This stage of cellular respiration produces pyruvate
glycolysis
this organelle stores and protects DNA
Nucleus
A tick biting a dog is an example of this type of interspecific symbiosis
Parasitism
This stage of photosynthesis absorbs sunlight energy
Light Dependent Reaction
these hydrocarbon molecules are solid at room temperature
saturated fats
NADH and FADH2 are produced at this stage of cellular respiration
Krebs Cycle/ Citric Acid Cycle
This organelle is responsible for synthesizing glucose from sunlight energy
Chloroplast
This type of organism is responsible for breaking down dead/decaying plants and animals
decomposers
This molecule is a high-energy electron carrier
NADPH
Methane is an example of this type of molecule
non-polar molecule
The purpose of lactic acid fermentation is to.....
Recycle NADH to NAD+ for glycolysis when there is no oxygen
This organelle synthesizes primary proteins slated for use in the cell's cytoplasm
Free ribosomes
Photosynthetic and Chemisynthetic organisms are in this group of organisms
Producers
This molecule is oxidized in the light dependent reactions
Water
Water molecules are attracted to each other because...?
Polar covalent bonds cause hydrogen bonding between molecules
Carbon dioxide is produced as a byproduct of breaking down this molecule in respiration
glucose
This organelle creates vesicles for exocytosis
The golgi apparatus
These two processes recycle carbon in organisms
Cellular respiration and photosynthesis
In the reduction stage of the Calvin Cycle, 3-PGA is reduced by this molecule
NADPH
these two polysaccharides are indigestible for humans
chitin and cellulose
A patient comes to the hospital complaining of muscle weakness. Testing indicates high levels of lactic acid in their blood. How would you treat the patient?
Give them oxygen
Taking the drug ecstacy can cause a person to experience extreme thirst, resulting in an overconsumption of water. This can be extremely dangerous and could kill the person. Explain why drinking too much water could be dangerous.
Drinking water is hypotonic to our body's cells, and too much water in the body can rush into cells and cause the cells to lyse (burst). This is especially dangerous for brain cells.
Name the two organisms that were grown in the closed beaker bag ecosystem this fall.
Brine Shrimp (Artemia salina) and Nannochloropsis algae
A scientist tests the growth rate of two plants when exposed to green light: sugar maples that have green leaves, and Japanese maples, that have red leaves. One of the two plants dies. Which one is it and why did it die?
The sugar maple dies. It is green so it does not absorb green light well. It cannot photosynthesize, and therefore dies.
