Cell Stucture
What is the major principle of the cell theory?
All organisms are made up of cells.
What is the difference between a hypotonic, hypertonic, and isotonic solution?
Hypotonic = filled with water, Hypertonic = shrunken (no water), Isotonic = equilibrium of water flow inside and outside the cell
What bond is broken in order to provide the energy needed for cell functions?
ATP - phosphate bond #3
What happens during Interphase?
DNA is copied.
Does binary fission take place in multicellular organisms?
No. Only single-celled (prokaryotes).
Which organelle is the storehouse for most of the cell's genetic information?
Which cell process requires no energy from the cell?
Facilitated diffusion
What happens to the sugars that are made during photosynthesis?
Used for cellular respiration.
If a cell cannot move enough material through its membrane to survive, then what does this say about its surface area to volume ratio?
Surface area to volume ratio is too small.
Can malignant tumors cause tumors in other parts of the body?
Yes.
Which organelles supply energy to the cell?
Mitochondria
Which organelles are involved in the process called endocytosis?
Vesicles
What are the products of the Krebs cycle?
Carbon dioxide and ATP
Why do the cells lining the stomach divide more quickly than those in the liver?
Undergo more wear and tear.
Before cellular respiration, glucose must be broken down by the process of...
Glycolysis.
Which process occurs inside the chloroplasts?
Photosynthesis
Where do light-dependent reactions take place?
Thylakoid
An electron transport chain that produces ATP is part of what two processes?
Cellular respiration and photosynthesis.
During which stage does the cytoplasm of a cell divide?
Mitosis.
The part of cellular respiration that needs oxygen takes place inside the...
Mitochondria.
What are the two types of protein transport?
Active and Passive Transport
Which molecule in the food we eat is most commonly broken down to make ATP?
Carbohydrates
What must a cell pass first in order to proceed to mitosis from the gap 2 stage of the cell cycle?
Pass a critical checkpoint.
starfish.
In which process is lactic acid formed when there is not enough oxygen present for cellular respiration to take place?
Fermentation.
