Organelles
How do molecules move across a membrane?
Lights- Camera- Action
Sugar Rush!
It's a CYCLE

As the cell size increases the surface area- to volume ratio _____________________.
decreases
100
Define the function of the cell membrane.
Protect the cell regulate what goes in and what goes out
100
What organisms undergo photosynthesis?
autotrophs
100
What goes into cellular respiration? What comes out? What is the total number of ATP produced?
Reactants= O2 and glucose Products= CO2 Total ATP ~ 38 ATP
100
Order the flow of energy rabbit, sun, grass, deer
sun, grass, rabbit, deer
200
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells have DNA in the cytoplasm (in a loop). Eukaryotic cells have membrane bound organelles.
200
Define diffusion
Molecules moving down the concentration gradient (from high to low) gas molecules move using diffusion
200
What is the equation for photosynthesis?
6H2O + 6 CO2 --> C6H12C6
200
What is glycosis?
1st step- glucose breaks down with the help of ATP to make pyruvate NADH (energy is carried) produced
200
Explain why autotrophs and heterotrophs depend on each other?
Autotrophs need CO2 we produce and we need O2 and glucose they produce
300
What structure do plant cells and bacteria have in common?
Chloroplasts (to perform photosynthesis)
300
True or False: Osmosis is the process which water moves from low to high concentration gradients
False
300
What happens on the first stage of photosynthesis?
Light excites H2O molecules, releasing H+ molecules
300
What happens in the Kreb's cycle?
Pyruvate goes in, CO2 is produced NADH and FADH2 is produced
400
Match the following organelles with their functions: Organelles: Ribosomes, golgi apparatus, Rough ER, smooth ER Functions: Make proteins Site of protein synthesis package vesicles site of fatty acid and phospholipid synthesis
Ribosomes- Make proteins Rough ER- Site of protein synthesis Golgi apparatus- package vesicles Smooth ER- site of fatty acid and phospholipid synthesis
400
Define active transport
The movement of molecules from low to high and requires energy
400
What happens in the Calvin Cycle?
CO2 molecules split and make glucose with the help of ATP and NADPH
400
What happens in the electron transport chain?
Electron carriers go down the membrane gradient creating ATP
500
What are the different organelles that are in plant cells compared to animal cells?
Chloroplasts vacuole cell wall
500
What is the difference between passive and active transport?
Passive transport does not require ATP and active transport does ( needs energy)
500
What is the product of the Calvin Cycle?
1 glucose molecule
500
What happens when oxygen isn't present?
Lactic acid fermentation- pyruvate --> lactic acid Alcohol fermentation- Pyruvate --> ethanol
