The ATP that is generated in glycolysis is produced by substrate-level phosphorylation, a very different mechanism than the one
Lostsunrise [7]

Answer:

TP synthesis in glycolysis: substrate-level phosphorylation

Explanation:

-One of the substrates is a molecule derived from the breakdown of glucose

-An enzyme is required in order for the reaction to occur

-A bond must be broken between an organic molecule and phosphate before ATP can form.

Incorrect:

-The phosphate group added to ADP to make ATP comes from free inorganic phosphate ions.

-The enyzmes involved in ATP synthesis must be attached to a membrane to produce ATP.

An endangered species of fish has a population that is decreasing exponentially:A=A0 e^kt The population 10 years ago was 1700.
bija089 [108]

Answer:

The correct answer is E. none of the above.  The population will drops below 100 when t ≥ 38.

Explanation:

Given A= A0 e^kt. The population 10 years ago is A0, the population today is A(10), and we have to find the value of "k" and then the time when population drops below 100.

So, A(t) = 1700 e^kt ⇒ A(10) = 1700 e^k(10) ⇒ 800 = 1700 e^k(10) ⇒

800/1700 = e^k(10) ⇒ln (800/1700) = k(10) ln e ⇒ -0.754/10 = k ⇒

k = -0.0754.

Now you have all the parameters, so you can find the time at which the population drops below 100.

A(t) = 1700 e^kt ⇒ 100 = 1700 e^(-0.0754)t ⇒100/1700 = e^(-0.0754)t ⇒

ln(100/1700) = (-0.0754)t ln e ⇒ [ln(100/1700)]/(-0.0754) = t ⇒

t = 38.

So, the population will drops below 100 when t ≥ 38.
