Answer:
Olfactory system
Explanation:
In an olfactory system, odor molecules are perceived by the olfactory receptors. These odor molecules are nothing but the chemicals which are then transduced as chemical signals into the electrical signals and sent to the brain. The brain perceives these electrical signals as smell.
The odorant particles bind to the specific receptors located at cilia which then signal through the G protein Gαolf which then activate adenylate cyclase. Adenylate cyclase leads to cAMP production which then open a cyclic nucleotide-gated ion channel through which both sodium and calcium ion entern into the cell. Calcium ion then activates chloride channels and thereby causing transduction of electrical signal
Answer:
NADH, pyruvate.
Explanation:
The fermentation process occurs in the cytoplasmic matrix.
Thanks to the H+ that are recovered from the oxidation of NADH to NAD +, they bind to pyruvic acid to change its conformation and transform it into lactic acid.
Two types of fermentation occur:
- Lactic
- Alcoholic, which releases ethanol + CO2
This is the reaction:
C6H12O6 + 2 Pi + 2 ADP + 2 NAD → 2 CH3-CH2OH + 2 CO2 + 2 ATP + 2 NAD
Answer:
Their evolution came before eukaryotes
Explanation:
Prokaryotes do not have a nucleus nor membrane bound organelles. Both prokaryotes and eukaryotes are unicellular (one cell) organisms. This leaves us with our answer. Hope this helps!
