BIOL4 Biology Unit 4 Exam - 13th June 2011

There were no homozygous chocolate cats.

for the ticky one i ticked all three for produce atp, found in organelles was photosynthesis( chloroplasts) and aerobic respiration ( mitochondria)
and for electron transport chain i put aerobic respiration ( stage 4) i think thats 3/3 can anyone see any mistakes??

1. For humans, I said they need it for many biological processes, such as mitosis and DNA replication, and they also require lots of ATP to maintain body temperature.

2. I ticked all of photosynthesis (PSS), all of aerobic respiration and for anaerobic respiration, I only ticked that it makes ATP. But I was confused on the PSS one, because it does make ATP but that gets used up, so does it count? Mitochondria and Chloroplast are both organelles. Can't remember what the last row was for

3. I put as one increases, the other decreases.

4. The mites eat the pathogens so the chicks are less likely to catch a disease and die, so this increases breeding success.


Does anyone agree with my points? If you disagree, tell me what you put instead please?

thats exactly what i thought so therefore its not possible

For the first question, did people get: the first row all ticks, the second row all ticks, and 2 tciks for row 3 (anearobic respiration doesnt involve ETC)?

what did you guys put for why the animal waste digester thing had to be cooled? had no idea

no for the first row it is all ticks, for the second row anaerobic respiration doesn't tske place in an organelle, it's the cytoplasm and for the third row aerobic respiration has the electron transport chain but i thought photosynethsis shouldn't be ticked because thats just electron transfer chain

hey yeah i agree!!!
but the ticky one i got wrong
i ticked all of photosynthese
for anaerobi i ticked the first one (first two should have been ticked cos it makes atp and is in organelle)

isn't anaerobic in the cytoplasm coz its just glycolysis??

I put the micro organism respires so releases heat energy and if the heat built up it would denature its enzymes.
