Differences between RNA and DNA
(3)
1.RNA has Uracil, DNA has Thymine
2. RNA is Single-stranded, DNA is double – stranded
3.RNA sugar is Ribose, and DNA sugar is Deoxyribose
Which is matched incorrectly to its function in the cell?
Golgi – packaging and shipping of proteins
Rough ER – Synthesizing proteins
Lysosomes – replicate DNA
Mitochondria – cellular respiration
What are Lysosomes? Lysosomes breakdown and recylce organic molecules.
Exocytosis – secreting out of cell (enzymes, neurotransmitters, hormones)
Endocytosis – engulfing stuff into cell (bind to receptor proteins)
The type of bond that leaves the bonded atoms with partial charges. (Uneven sharing of electron).
What are polar Covalent Bonds?
1) This type of reaction that connects molecules by removing water. (water is produced)
2) type of reaction that breaks apart molecules by adding water. (water is used up)
1) What is dehyrdation synthesis
2) What is hydrolysis
2 semiautonomous organelles
Inside a dialysis bag you have a 20% glucose concentration and a 10% NaCl concentration. Outside the bag there is a solution with 5% glucose concentration and 5% NaCl concentration.
Which way will water, NaCl, and Glucose move??
water- moves inside bag (hi (90%--->(70%) lo)
NaCl (Na+ C-) will move outside the bag (hi (10%)--> lo (5%))
Glucose: does not move
