Answer:
The given statement is false.
A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.
The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).
The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.
Answer:
Ok, how is this a question?
The statement is true though!
The correct answer is: a. A site in DNA that recruits the RNA Polymerase
Promoters are regions of DNA molecule located near the transcription start codons of genes, usually upstream on the DNA with the function to initiate DNA transcription. Promoters contain specific DNA sequences (e.g. TATA boxes) that are binding sites for the enzyme RNA polymerase and transcription factors that recruit RNA polymerase. Transcription factors can regulate gene expression and act as activators or repressors depending on sequences that attach to specific promoters.
Answer:
36 ATPs
Explanation:
Cellular respiration starts with glycolysis wherein glucose is broken down into two molecules of pyruvate. The process of glycolysis forms two molecules of ATP by substrate-level phosphorylation for each glucose molecule. Both pyruvate molecules are converted into acetyl CoA to enter into the Kreb's cycle. Kreb's cycle forms two ATP molecules by substrate-level phosphorylation. NADH and FADH2 formed during glycolysis and Kreb's cycle are oxidized by the electron transport chain. This process also forms as many as 34 ATP molecules. If acetyl CoA is not formed, the total ATP gain per glucose will be only 2 ATP molecules (from glycolysis only) which is 38-2= 36 less than the total.
An animal cell will only have a cell membrane, a plant cell will have a cell membrane and a cell wall
