Insulin increases the rate of protein synthesis and therefore lowers the blood amino acid concentration. Someone lacking insulin (e.g. type I diabetics) would see an increase in their blood amino acid concentration.

Re: Help in identifying growth

Alrazi, how did you identify it as a Chara? I would like to know please. My guess was a Chlorophyte (green alga). Chlorophytes are usually unicellular, whereas charophytes can form colonies, or multicellular bodies, with usually multinucleate filaments. So I would agree with alzari and say it is pr...

Re: Difference between T-Cell and Phagocyte?

I just joined this forum. I tried to use one of the two facts, biology noivce, as my username, but it was already taken. Then I used the other, here by chance. I liked your clarification for phagocytosis and endocytosis - answered one of my long time questions. I have some further questions if you ...

Re: electric shock and memory

It affects short-term memory because it is stored as transient neural excitations in the hippocampus or amygdala (for emotional memory). Long-term memory, on the other hand, is stored in some form of synaptic plasticity, such as long-term potentiation or long-term depression and therefore is not aff...

Re: measuring action potential outside of neuron

It will measure 0 mV, because the ion concentration will be the same at both electrodes.

From wikipedia: Based on the growth profiles under different O2 concentrations, the Bifidobacterium species were classified into four classes: O2-hypersensitive, O2-sensitive, O2-tolerant, and microaerophilic. The primary factor responsible for aerobic growth inhibition is proposed to be the product...

Re: Cell Question

1. An overproduction of a particular product means that the cell is allocating energy and resources to produce what is not necessary, or what might even be toxic in higher quantities, at the cost of producing other substances that may be more vital for the cell's survival. 2. Most likely this is the...
