Cell Structure & Function
What is the classic example of a prokaryotic cell?
bacteria
What 2 biomolecules carries a lot of energy?
Carbohydrates and Fats
What organelle's main function is cell transport?
Cell Membrane
What are the 3 phases of the cell cycle?
Interphase, Mitosis, Cytokinesis
What do you have to write at the beginning of every class in your interactive notebook?
Learning objective + essential questions
What does "KARYO" mean in pro (karyo)tic & eu(karyo)tic cells?
What is the monomer of proteins?
Amino Acids
How is homeostasis related to cell transport?
"end goal", when molecules reach homeostasis, they stop moving.
What happens during the S phase (of interphase)?
DNA replication/chromosome duplication
How do you contact Mr. Vo and get a quick reply?
Remind
Name 4 organelles or structures that prokaryotic and eukaryotic cells have in common?
ribosome, cytoplasm, genetic material (DNA/RNA), and cell membrane
What biomolecules are used to communicate information between cells?
nucleic acids
You know that molecules when moved from area of high concentration (#molecules per 1 space) to an area of low concentration requires NO ENERGY. Explain why this process requires no energy...
The process is natural to the universe, just like a ball being dropped due to gravity.
What is the phase where the chromosome / 2 sister chromatids separate towards the poles?
anaphase
What does Mr. Vo expect if you are turning in late work?
Quality work - you gave a good effort. Mr. Vo has to spend extra time to grade your late work.
Which organelle is used to make energy in eukaryotic cells?
Mitochondria
What biomolecules is/are found in peanut butter?
proteins, carbohydrates, fats
Facilitated diffusion is a form of passive transport to move biomolecules, but requires EXTRA help to do so. What structure is involved in this "help" to transport molecules?
protein carrier
What is the structure that forms during telophase:
signaling the cell is ALMOST dividing into 2 separate daughter cells?
cleavage furrow
You should be taking notes during lecture & class activities - when you learned something...how should you be taking notes?
Things Mr. Vo says many times - it's important or when you encounter them in your work.
According to endosymbiotic theory used to describe history of life, organelles were once what organisms?
bacteria
A boy has not eaten anything in 1 week. You see the boy is super skinny and does not have a lot of muscle mass. You ponder that all his biomolecules are being "burned" to give him energy to stay alive. List the 4 biomolecules in order of quickly used energy to molecules that are burned as a last resort?
1) carbohydrates
2) fats
3) proteins
4) nucleic acids
You have a cup with a gummy bear inside it. The cup is hypertonic (46% salt) to the gummy bear (28% salt). What will happen to the gummy bear inside the cup if it is left inside for 1 hour?
Gummy bear will sag/wilt and eventually be no more. This is due to the movement of water from an area of high concentration (inside the gummy bear) to the cup (outside).
Cancer cells are immortal (they don't die) and keep dividing without going through interphase. How does this violate the cell cycle, based on our talks about how the cell cycle behaves?
Things have to hit milestones/key events IN ORDER before proceeding to next events. Cancer cells undergo mitosis VERY OFTEN without any control.
What does Mr. Vo want you to get out of biology this year?
1) learn how to write to express oneself
2) learn how to organize information (in your mind & in your notebooks)
3) learn how to be active thinkers & learners
4) learn how to manage your time
5) be inspired in science, or at least know how science is important in daily lives...
