Give the Monomer and function of Carbohydrates
Monosaccharides - quick energy
100
An enzyme is a _______ which means it is something that speeds up a reaction while remaining unchanged.
Catalyst
100
What is the main organelle that Eukaryotes have that Prokaryotes do not have?
Nucleus
100
What does Homeostasis mean?
Maintaining a stable internal environment
100
Do all living things do cellular respiration?
Do all living things do Aerobic cellular respiration?
Does ATP contain Carbon, making it an organic molecule?
They need ATP/Energy.
NO
YES
100
Monomer and give two functions of Lipids. One of them has to include what part of the cell do they make up.
No monomer. Main component of cell membrane + long term energy + insulation + protection.
100
What is the term for the change in shape of an enzyme and what are two conditions that affect how they work.
Denature - Temp, pH, Concentration.
100
T/F Plants have both chloroplasts and Mitochondria
T
100
What is the structure that is the most important in keeping cells in homeostasis
Cell membrane
100
What is the product from photosynthesis that makes up the energy for all organisms in an ecosystem?
Glucose
100
An enzyme's Ideal temperature is around 30 C. It's currently in 20 C. What would help speed up the reaction?
A - Raising the temp by 5 C
B - Raising the temp by 20 C
C - Dropping the temp by 10 C
A Raising the temp by 5C - this speeds up the reaction without running the risk of denaturing the enzyme
100
What organelle do all living things have and what do they do?
Ribosomes - make proteins
100
What is the term for the flow of water from high concentration to low concentration of water
Osmosis
100
Three things needed for photosynthesis
CO2 + Water + Sunlight
200
Monomer and function of proteins
Amino Acids and they are the macro group that makeup enzymes, makeup structure of most of the body.
200
What does activation energy mean and how do enzymes affect it?
Activation Energy - The energy required to start a reaction. Enzymes lower the activation energy
200
What is the function of the lysosome
Breaks down waste
200
In Active Transport what direction do molecules flow in regards to their concentration. What molecule is used to make this happen?
From Low to High concentration; ATP
200
Glucose is a form of ______ Energy.
Chemical
300
What makes up the backbone of the DNA and what is in the middle
Sugar Phosphate Backbone and Nitrogen bases.
300
What range of pH do both of these enzymes work in?
4.5 - 5.5
300
Why does a plant cell have a central Vacuole
They need to store water in case of a drought.
300
Is water moving in both directions? Which direction (into or out of the cell) is more water moving?
Yes, out of. Even though things move from a H to L concentration there is usually movement in both directions!!
300
What makes ATP for a plant cell?
A - the Chloroplast
B - the Mitochondria
C - the Nucleus
B
400
What are three organelles that a tree has that a squirrel doesn't have?
Cell Wall, Large Central Vacuole, Chloroplasts.
400
What things get continuously recycled throughout photosynthesis and Cellular Respiration
Carbon/Carbon Dioxide and Water
500
Group that DNA is in, monomer, what is the sugar in DNA, what shape is it in (_______ Stranded, ______ Helix)
Nucleic Acids, Nucleotides, Deoxyribose, Double Stranded Double Helix.
500
What are the two main functions of the cell membrane and what cells have them?
Structure and they help maintain homeostasis (Transport of materials is OK).
ALL Cells have cell membranes
500
In a healthy ecosystem, the amount of Carbon in the air remains at a stable level. How does that happen?
The amount of carbon released through cellular respiration is the same as the amount of carbon taken in during photosynthesis.
