PE Exam '08

[juzzyfizzle]

With Question 4 I chose B, as Phosphate Creatine can produce the most ATP.
(Not sure what lipids are but yeh)
Question 8 I chose C.
13 - B.

Otherwise I got the same answers as you akkxn

Nah JB, lipids are fats.

[studyhound]

anyone else say lactate ions would contribute to the climbers muscular inhibition?

Nah, lactate is actually aids in energy production.

"endurance training teaches the body to efficiently use lactic acid as a source of fuel on par with the carbohydrates stored in muscle tissue and the sugar in blood"

fair enough

[mtwtfss]

Think all those MC answers are right.

Also during short answer, two reasons why a 400m runner declines in speed apart from lactic acid.

PC depletion

and i said hydrogen ions, but i've been shot down heaps about this, as it is related to LA closely, but i'm arguing its different.

Other answers i've heard include things even like choking, but im not sure about that.

Thoughts?

[bucket]

I don't think hydrogen ions will be accepted.
I wrote inorganic phosphates and ATP depletion.

[mtwtfss]

DAMMIT

[michaelc8]

i sed C for question 9. cos ther all training principles
and i sed calcium for the climber one i think :S

Jordan Berry is that you? LOL

ya I wrote accumulation of Pi and ADP and PC depletion

I've heard that the lactic in lactic acid refers to "lactate" and the acid refers to the "hydrogen ions"

[michaelc8]

lol yeh pc only gives 1 its the worst, protein gives 17 so i sed that and i didnt know wat lipids were so i just crost it out lol

as if it wont they are completely different lacic acid is a positive thing that can be used in for energy. H+ ions are what causes that fatigue they are completely separte things although they do accumulate at the same time and rate.

im pretty sure Lactic acid is only found in the muscles and lactate is lactic acid in the blood

So when lactic acid is moved from the muscles into the blood, it is separated into lactate and hydrogen ions. Any idea?

Lactic Acid definitely breaks down into Lactate and H+ so doubt you will get the mark for H+.

In regard to question 9 Im pretty sure i answered D (Duration Intensity Maintenance) and although now A seems like the obvious choice and im pissed off at myself is D not also correct seeing maintenance is training at least 2 times per week as is in the training program? Can someone either confirm or tell me why im wrong? Cheers
