Bunch of BIo quesion

[joonkimdds]

1. the main energy transformers of cells r
a) found within the golgi apparatus
b) mitochondria and chloroplasts (correct)
c) located in the nucleus
d) found in peroxisomes

i don't know why it says "(correct)" on B, does that mean test maker accidentally gave me the answer?

2.which of the following do both chloroplasts and mitochondria have in common?
a) both r involved in photosynthesis
b) some DNA is present in both
c) neither have membranes
d) both r located in the nucleus

3. plasma membranes have selective permeability - allowing some substances to pass more easily than others. which of the following types of molecules r the major structural components of the cell membrane?
a) phospholipids and cellulos
b) nucleic acids and proteins
c) proteins and cellulose
d) phospholipids and proteins.

4. Alanine, arginine, aspartic acid, cysteine, glutamic acid, valine, tyrosine, tryptophan, thereonine, serine, praline, phenylalanine, methionine, lysine, leucine, isoleucine, histidine, gluycine, glutamine, glutamic acid, and asparagines are all names for different monomers of a particular type of macromolecule. what is the name of the type of monomer which they represent?
a) proteins
b) amino acids
c) enzymes
d) proteinases

B - Becuase they change energy.

2.which of the following do both chloroplasts and mitochondria have in common?
a) both r involved in photosynthesis
b) some DNA is present in both
c) neither have membranes
d) both r located in the nucleus

B is the correct answer- Look up endosymbiosis.

3. plasma membranes have selective permeability - allowing some substances to pass more easily than others. which of the following types of molecules r the major structural components of the cell membrane?
a) phospholipids and cellulos
b) nucleic acids and proteins
c) proteins and cellulose
d) phospholipids and proteins.

D - this is simple cell stucture stuff. You OUGHT to know this stuff already.

4. Alanine, arginine, aspartic acid, cysteine, glutamic acid, valine, tyrosine, tryptophan, thereonine, serine, praline, phenylalanine, methionine, lysine, leucine, isoleucine, histidine, gluycine, glutamine, glutamic acid, and asparagines are all names for different monomers of a particular type of macromolecule. what is the name of the type of monomer which they represent?
a) proteins
b) amino acids
c) enzymes
d) proteinases

B - These are all the names of the different amino acids.

These were simple questions, you should not be stressing about these. Read the entire KBB (kaplan blue book), and the things you don't understand underline or hightlight. Then read and try to understand, if you still don't post away. Good luck.
