Gah! I can't stand showoffs!! What is all this now? Honestly, give the rest of us a complex why don't you.

answer the question, woman. you can buzz him on YIM

My own Question - Where can a dummy dumb get a cheat sheet or cliftnotes version for this?

lol, sparknote.com mehn, that helps me a lot with those boring books

*Morenike:

ok, I knew it. but I wasn't sure.
I was thinking it couldn't be work since energy is the capacity to do work


@post


This is an example of. . . .

A)Noncompetitive inhibitor
B) competitive inhibitor
D)cofactor
D)coenzyme
E) an intermediate

What the heck is this? Pacman?
In as much as I suck at bio, my logical guess is
oloun nipe kin mu yi, mo mu yi t'oloun sope kin mu, oun de ni

A

Well, johnbull my son I sent you to school but you don't know how to spell your name.
Showoffs don't bother me one bit.

A

Lol, you're right. It's noncompetitive because that blue molecule did not bind itself to the enzyme's active site. It binds itself to another location on the enzyme. Which changes the shape of the active site, so the substrate (green) won't be able to bind to the enzyme. The molecule, in another word, denatures the enzyme.

hmm, smart!

A fish breathes through its

A) Scale
B) Wings
C) Gills
D) Head
E) Tail

Gills!

I think

C) Gills. I rem. this when I used to watch The MAGIC SCHOOL BUS

A series of enzymes catalyze the reaction X-->Y--> Z-->A . Product A binds to the enzyme that converts X to Y at a position remote from its active site. This binding decreases the activity of the enzyme.

In this example, substance X is

A) coenzyme
B) an allosteric inhibitor
C) a substrate
D) an intermediate
E) the product

Two independent clauses joined only by a comma (written as two words)

A)semicolon
B)indefinite pronoun
C) antecedent
D)run-on
E)common splice

I win! I know book!

Judging from what you said before, wouldn't that be a substrate?

Sisi this is said to be your specialty, won't you come and reply

Assay of Enzyme Activity Increasing Substrate, Constant Glyphosate

Substrate Concentration (mg/ml) 10 15 20 25 30
Relative enzyme activity(%) 20 40 60 80 100


The data shows that glyphosate most likely

A)acts directly on one of the amino acids
B)is a competitive inhibitor of the enzyme-catalyzed rxn
C)does not affect activity concentration below 10 mg/ml
D)indirectly alters the configuration of the enzyme's active site
E) acts as a noncompetitive inhibitor of the pathway

Cell wall is to support and protection as chromosomes is to

A)chief site of cellular resp.
B)formation of ATP
C)genetic control information
D) enzyme inhibition




Oh come on!!

What coefficients must be placed in the blanks so that all atom are accounted for in the products.

___C₆H₁₂O₆ ---------> ____ C₂H₆O + ____CO₂

a)1;2
b)2;2
c)1;3
d)1;1
e) 3;1

2;2

those two are easy now. try the experiment question

H2O2:

2;2

How?

There are 3 blanks for instance, if you have 2 infront of glucose then you have 12 carbon atoms to account for on the left side of the equation.

If u put 2 on both blanks on the right you only account for 6 carbon atoms.

<<snip>> oops sorry, i figured it out now. 2;2 is correct.

I'll go with E, just like I went with A before

Ok.

Lol, not this time, it's B.

In an organism, the energy available to do work is called free energy because

A) it can be obtained with no cost to the system
B)it can be spent with no cost to the universe
C)the organism can live free of it if necessary
D)it is available for work
E) It is equivalent to the system's total energy

I believe free energy is energy available for work.

The correct answer is (B)

lexicon:

The correct answer is (B)

H202 is correct. It's not B

Ah! Yes the token normal question out of 60 something genius questions. Thanks ^{for nothing}

Acid, the answer would be E if E was Comma Splice


You guys give us regular questions now! All this --->>2CC and 2AA<<<----- is no gelling with some of us.

The presence of cholesterol in the plasma membranes of some animals

A)enables the membrane to stay fluid more easily when the cell temp. drops
B) enables the animal to remove hydrogen atoms from the saturated phospholipids
C)enables the animal to add hydrogen atoms to unsaturated phospholipids
D)makes the membrane more flexible, so it can sustain greater pressure from within the cell
E) makes animals more susceptible to circulatory disorders
