Answer:
Explanation:
I think it is: acetylcholine (neurotransmitter) - motor neuron - contract
second question: diffusion because of opening of ca2+ channels
Answer:
a) the molecules can be found in the picture below
b) (i) isocitrate lyase ( isocitrate to glyoxylate)
(ii) malate synthase (glyoxylate to malate)
c) Glyoxylate cycle do no exist in animals
Explanation:
b) in the glyoxylate cycle isocitrate lyase helps in conversion of isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.
c) Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.
To bring oxygen in the body because it is a respiratory organ fish
