X Incorrect.
Suppose that an uncatalyzed reaction is spontaneous because AG has a value of -10 kcal/mol. An enzyme that catalyzes the reaction is identified. What effect will the enzyme have on the rate of the
reaction? Choose all that are correct.
The enzyme increases the AG value.
The enzyme increases the rate of reaction.
The enzyme decreases the rate of reaction.
The enzyme decreases the AG value.
The enzyme raises the activation energy.
The enzyme lowers the activation energy.
Question #1: Choanoflagelletes are a unicellular ancestor to animals. One observation to support
this hypothesis is the appearance of adhesion molecules that are key to the development of
multiceullarity.

Insects, mammals, and other animals

Jellyfish and their relatives (10,000)
} Sponges (10,000)
Choanoflagellates (150)
Despite their simple unicellular lifestyle they express adhesion molecules including cadherins
and lectins (King et al., 2003) but don't seem to have molecules that are typically found in the
extracellular matrix such as integrins or laminins (Williams et al., 2014).
Design a microscopy experiment to test the assertion that choanoflagellates have (some)
adhesion molecules and those molecules play a similar role in a closely related animal like
sponges.
Thank you in advance!Based on the model on the picture, please help me identify these (even with no explanation):1. What is free energy? What is its symbol?
2. For an exergonic reaction, what is the value of △G?
3. For an endergonic, what is the value of △G?
4 What are the factors that affect △G?
5. What is energy coupling? In a coupling reaction, what must be the overall value of △G?
6. What does the cell do with the energy produced from exergonic reactions?
7. What molecule does the cell use as an energy carrier? Draw its structure.
8. Why is it that this energy carrier is considered to be high energy containing phosphate?
9. Bond of this energy carrier of cells is broken through what?

- Help please. This question is specifically asking for the identification of the biomolecules that are attached to the sphingosine core, then we need to answer what bond causes those biomolecules to be connected to the sphingosine, what reaction created that bond (maybe addition or oxidation etc.), what were the starting materials and lastly what reagents or conditions are needed for the reaction to occur. Thank you!arrow_forwardEnzymes catalyze chemical reactions. What constitutes the active site of an enzyme? What are the turnover number (kcat), the Michaelis constant (Km), and the maximal velocity (Vmax) of an enzyme? The kcat (catalytic rate constant) for carbonic anhydrase is 5 × 105 molecules per second. This is a “rate constant,” but not a “rate.” What is the difference? By what oncentration would you multiply this rate constant in order to determine an actual rate of prod- uct formation (V)?
