Rough ER is studded with ribosomes and the Smooth ER has a smooth surface ..
Ethanol is produced by yeast under anareobic respiration.
When Glucose is converted into 2 Pyruvic acid yeast converts this into 2 Ethanol and 2 Carbon Dioxide.
Or simply.
C6H1206 + yeast -> 2C2H50H + 2CO2
Enzyme is zymase.
Hope this helps :).
Answer:
4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR.
5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit.
2) Dissociation of Ga from the G protein complex.
6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.
3) Production of a second messenger, like cAMP.
1) Activation of one or more cellular signaling proteins.
Explanation:
It is a signaling cascade initiated by G proteins. These G proteins function as molecular switches capable of activating signaling pathways in the presence of guanosine triphosphate (GTP), which is hydrolyzed in order to produce energy
It should be taken into consideration the presence of frameshift mutations. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and consequently in changed protein. But it is known that 3 nucleotides on mRNA code for the specific amino acid. If the number of inserted or deleted nucleotides is 3, it will result in the absence<span> of only 1 amino acid which is not expected to drastically change protein sequence.
Knowing all this, it can be concluded the following:
</span>
<span>-/-/+/-/- <u>OK </u>- Due to 4 deletions and 1 insertion, effectively only 3 nucleotides are missing.
</span>+/-/+ <u>Not OK</u> - Due to 1 deletion and 2 insertions, effectively only 1 nucleotide is added leading to the frameshift mutation.
+/-/+/- <u>OK </u>- Due to 2 deletions and 2 insertions, a number of nucleotides remain the same.
+/+/-/+ <u>Not OK</u> - Due to 1 deletion and 3 insertions, effectively only 2 nucleotides are added and the frameshift mutation occurs.
-/+ <u>OK </u>- Due 1 deletion and 1 insertion, a number of nucleotides remain the same.
<span>- <u>Not OK</u> - Due to 1 deletion, the frameshift mutation occurs.
</span>-/-/-/-/-/- <u>OK </u>- <span>Due to 6 deletions, it will be deleted 2 amino acids and the protein will be nearly normal.</span>
<span>+/+/+ <u>OK </u>- Due to 3 insertions, 1 amino acid will be added in excess.
</span>-/- <u>Not OK</u> - Due to 2 deletions, the frameshift mutation occurs.
Answer:
The lion could recieve injuries from the bigger prey that the smaller prey couldn't give.
for example, if a lion catches a rabbit, the rabbit could scratch its eyes, but if a lion catches some type of antelope or something, it could impale him with its horns.
