Which fact is most important in explaining how enzymes speed reactions?
High-energy collisions are less common than low-energy collisions.
Which properties of a substance contribute to its colour?
Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra.
Why are lactases important enzymes for mammals?
To break down the lactose in milk. Babies have this enzyme turned on, but in many parts of the world, those parts without a herding history, the enzyme is turned off in adults causing problems with the digestion of milk products.
All mammals feed their babies milk and this enzyme is needed to break down lactose in milk.
Why aren't amino acids considered a nutrient macromolecules?
If you have a(n) amino acid as a nutrient macromolecules, then everything that has it would be destroyed or killed, including fruits and animals, even people.
What does sexual active has to do with your hormones?
Hormones cycle through the month. They surge to prepare for menstruation, with that surge comes desire to have intercourse. Frequency of sex does not change the amount of hormones in your system.
The brick itself doesn't have any DNA but there undoubtably are bacteria and other microbes on it that do have DNA.
When humans breathe in carbon dioxide do they get sick etc?
As they breathe it out naturally they will breathe some back in. So the answer is no if in small doses
What will happen if red blood cells are transferred to seawater?
as u know, seawater is salty ,that is hypertonic..
when u place RBC in sea water it will swell and then burst.
Can a human digest wood if he takes a pill that contains a cellulose digesting enzyme?
Try it son. Send us the pictures!!
Which types of molecules are assembled at ribosomes based on the code in the DNA molecule?
Once a molecule of RNA has been synthesized during transcription, RNA molecule migrates to the ribosomes to become the "message" where the "Protein Synthesis" takes place, "reading" the sequence of nucleotides and synthesizing a molecule of protein or peptide. In this process, called "translation" participate the ribosome, tRNA molecules that carry amino acids to the assembly region of the translation complex.
Visual obsevation of barfoed's test?
A brick-red precipitate indicates a reducing monosaccharide. Some hydrolysis of disaccharides may lead to trace precipitates. Nat:)
Who is at risk for over nutrition and under nutrition?
over = junk food and no balanced diet, no exercise, positive family history, genes, etc
under = no balanced diet, chronic illness, anorexia nervosa, etc
What is the normal concentration of ketone bodies in blood?
It does not normally exceed 0.2 Mmol/L. So i d say it is less than 0.2 mMol/L
What organelles undergo cellular respiration?
Mitochondria are the organelles where cellular respiration occurs.
Where does the energy in biodiesel come from?
The energy comes from the plants because photosynthesis is being taken place
What are the major elements that form the glucose molecules?
The major elements that form the glucose molecule are carbon, hydrogen, and oxygen.
What are some hydrolyzable lipids?
Some hydrolyzable lipids include triglycerides, phospholipids, and sphingolipids. These lipids can be broken down into their component fatty acids and other molecules through hydrolysis reactions catalyzed by enzymes like lipases.
enzyme that catalyzes the shifting of a funtional group on a molecule from one position to another.
What do cold temperatures do to enzymes?
It usually lowers their effectiveness, i.e. slows the reaction rate.
When water flows from areas of high concentration to areas of low concentration through semi-permeable membranes; down it'd concentration gradient.
