Answer 1

After visiting a nature center, students were asked to contrast their observations based on location. Which of these students followed those directions?
a.
Amy: wildlife in or near water = turtles, crayfish, goldfish
non-water wildlife = fox, deer, bobcat
b.
Craig: wildlife with hair or fur = fox, deer, bobcat
wildlife without hair or fur = turtle, crayfish, goldfish
c.
Megan: mammals = fox, deer, bobcat
other = turtle, crayfish, goldfish
d.
Luke: observed = fox, deer, bobcat, turtle, crayfish, goldfish
not observed = water snake, squirrel

Answer 2

in glycolysis 2 ATP molecules, 2 NADH molecules, and 2 pyruvate molecules per 1 glucose molecule are produced!!!
each one of the 2 pyruvate molecules continues to the link reaction, which converts it into acetyl-CoA that will be qualified to enter Krebs' cycle... In this process, 1 CO2 molecule, along with an NADH are produced, which means: 2 CO2 and 2 NADH per glucose..
in the Krebs' cycle, the 2-carbon acetyl-CoA is converted into 2 CO2 molecules, and in the process, 3 NADH, 1 ATP and 1 FADH2 molecules are produced, which means: 6 NADH, 2 ATP and 2 FADH2 per glucose....
that sums up to 4 ATP, 10 NADH and 2 FADH2 per glucose
in oxidative phosphorylation, each NADH molecule is converted into 3 ATP, and each FADH2 into 2 ATP....
so 10*3 = 30
and 2*2 = 4, and since we have 4 ATP molecules 2 from each the glycolysis and the Krebs' cycle ------>
so 38 ATP molecules are produced in aerobic respiration...
In anaerobic respiration, only glycolysis takes place since there is no oxygen, so only 2 ATP molecules and 2 NADH are produced!!! the 2 NADH molecules are used in the pathway to repeat the same process!!!

Answer 3

Got it ?

Answer 4

Here the answer will be only 36 since in Muscle & Neuron cell Glycerol phosphate shuttle system is used which gives a Net gain of 36 ATP,

Answer 5

are uh getting my points ?

Answer 6

yes perfect and clear!! :) thank u
