Intro
What is symbiosis? Give an example
Relationship between living things in which at least one benefits.
Name the 3 subatomic particles
Proton, neutron, electron
Who discovered cells?
Robert Hooke
About how many ATP molecules does the ETC produce?
34-38 ATP
What always has to happen before the cell divides?
DNA is copied.
Describe the relationship between ecosystem and community
Community: living
Ecosystem: living and nonliving
What atoms and how many of each make up water?
2 hydrogen
1 oxygen
Describe diffusion.
Going with the concentration gradient. No energy required.
What are the two photosynthetic cycles?
Light dependent and Calvin
What are some differences between sexual and asexual reproduction?
Sexual: two partners lead to genetically variant offspring
Asexual: one partner leads to identical offspring
all living things are made of cells, all cells come from existing cells, cells are the basic unit of life
Describe the pH scale including vocabulary and numbers.
0-7 acidic
7 neutral
7-14 basic
Pushing a substance against its concentration gradient, requiring energy.
Come up to the board and draw the anatomy inside of a chloroplast.
Include stroma, thylakoid, grana.
What stage of mitosis does the nuclear membrane start to dissolve?
Prophase
List the six characteristics of living things.
Complex chemistry, made of cells, grow and develop, reproduce, respond to stimuli, maintain homeostasis
What is an isotope?
Atoms of the same element with a different number of neutrons.
Explain the concept of turgor pressure.
Turgor pressure increases as a vacuole enlarges.
What are the outputs of glycolysis?
Pyruvate, net of 2 ATP, 2 NADH
Describe the 3 phases of interphase
G1: cell growth
S: copying
G2: making organelles
Look at the graduated cylinder on your teacher's desk. How specific can you get your measurement?
To the nearest .2 mL
Describe the relationship between enzymes, reaction speed, and activation energy.
Enzymes reduce activation energy and speed up reactions.
Trace the journey of a protein from its production to its insertion into the cell membrane.
Ribosomes make the protein. The ER sends via a vesicle to the Golgi. The Golgi modifies it and sends it via vesicle to its insertion to the cell membrane.
Come to the board. Write the chemical equation for photosynthesis and cellular resp.
P: H2O + CO2 + sun = O2 + C6H12O6
CR: O2 + C6H12O6 = H2O + CO2 + ATP
Draw the four phases of mitosis on the board.
On board.
