Cellular Respiration
Where the process of cellular respiration takes place.
mitochondria
Quadruple points
Identify two types of organisms that use photosynthesis to make their food.
plants, algae, cyanobacteria, phytoplankton, some protists
This cycle moves a molecule that is essential for life. It is also one of the main ways that hydrogen and oxygen cycle through the Earth.
water (H2O) cycle
Triple points
Describe the difference between reactants and products in a chemical reaction.Reactants are the inputs in a chemical reaction and products are the outputs in a chemical reaction.
The molecule produced during cellular respiration that organisms use as energy for all metabolic activities to stay alive.
ATP
The energy for photosynthesis comes from this.
The sun
Triple points and point donation
Matter on Earth is ________ while energy ______ through living and nonliving things.
recycled, flows
Double points
1. Identify a biotic reservoir for any biogeochemical cycle.
2. Identify an abiotic reservoir for any biogeochemical cycle.
1. Any living thing
2. atmosphere, ocean, rocks, soil
These types of cells have lots of mitochondria because they are constantly working.
muscle cells
This gas is used for photosynthesis.
CO2
Where did most of the elements on Earth come from?
stars
What is the name for all of the chemical reactions that keep organisms alive?
metabolism
What are the reactants that are needed for cellular respiration?
glucose and oxygen
How was the ancient Earth's atmosphere billions of years ago different than it is today in terms of the main gases that compose it?
There was much less oxygen.
This nutrient cycles through biotic things and abiotic things like the atmosphere and rocks. It is often called the molecular backbone of life because it is the foundation for all biomolecules.
carbon cycle
This is the process that some prokaryotes use to make their own food using the energy found in certain chemicals.
chemosynthesis
Biologically usable energy comes in the form of this molecule.
ATP
Which part of a plant contains the most chloroplasts for photosynthesis?
the leaves
This cycle involves the atmosphere as its main abiotic reservoir.
nitrogen cycle
What is released when the chemical bonds within molecules are broken?
energy
Double points and point donation
Cellular respiration makes energy by breaking the _______ within glucose.
chemical bonds
This is when plants do the most photosynthesis.
During the afternoon when the sun is strongest.
During the late spring/early summer when the days are longest.
This cycle's element can be found in DNA, RNA and ATP within its biotic reservoirs, but it cannot be found in the atmosphere.
phosphorus
Briefly define each of the following terms:
Evaporation
Condensation
Precipitation
Evaporation = liquid water turns into water vapor
Condensation = water vapor turns into liquid water
Precipitation = any form of water that falls from the atmosphere onto Earth's surface
During ________ cellular respiration cells run low on oxygen and produce less ATP and more ________ as a byproduct.
anaerobic, lactic acid
Identify the reactants of photosynthesis. (3)
Carbon Dioxide CO2
Water H2O
Sunlight
Which two elements are main ingredients in plant fertilizer?
nitrogen and phosphorus
1. Describe the difference between catabolic chemical reactions and anabolic chemical reactions.
2. Identify an example of a catabolic reaction and an example of an anabolic reaction.
1. Catabolic reactions break down bigger molecules into smaller ones and release energy, while anabolic reactions build bigger molecules from smaller ones and require energy.
2. Cellular respiration is catabolic and photosynthesis is anabolic.
