Like a key in a lock, the shape of the _____ must bind with the _____ of the receiving neuron.
likoan [24]

Neurotransmitters are the chemical molecules, which help in transfer of the signals from one neuron to another. Inside the neurons, the signals are transferred as electrical signals, but at junction of two neuron, which is known as synapse, the signals are transferred in chemical forms.

These neurotransmitters have a definite shape and are recognized by the receptors present in the receptor site of the succeeding neuron. The neurotransmitters from the synapse binds to the receptor site of the receiving neuron. binding of the neurotransmitter to the receptor causes excitation of the receiving neuron, which also known as postsynaptic neuron.

Hence, Like a key in a lock, the shape of the neurotransmitter must bind with the receptors of the receiving neuron.

Explain how he interaction between mRNA codons and tRNA codons anticodons codes for a specific amino acid
Julli [10]
<span>The interactions between the mRNA codons and the tRNA anticodons  codes for a specific amino acid is by, it is the job of the tRNA to start working after the mRNA has able to have its own complementary copy. The mRNA will undergo to the nucleus and will move out, in order to go the rrna. The three nucleotides codes the specific amino acid of the trna. The trna and the mrna will be matched, it will now release the amino acid in the trna that wil form a peptide bond. When the mrna is able to be decoded to form an amino acid, it will now have the ability to break and make proteins in different structures.</span>

What assumptions did Engelmann make in order to conclude that red and violet-blue light were more effective than green light in
iren [92.7K]

Answer:

The distribution of chloroplasts in each algae cell was approximately the same.

The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.

Explanation:

Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.

The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
