As electrons move along the chain, hydrogen ion are pumped from the stroma of the chloroplast into thylakoid lumen. these leads to creation of proton gradient in thylakoid lumen with the potential energy that will be used to synthesize ATP by enzyme ATPase in the process referred to as rotational catalysis. both chloroplast and mitochondria use electron transport chain to pump protons across the membrane and both enzyme ATPase to produce ATP using proton gradient created in the process of transport of hydrogen ions. the main existing between the electron transport chains of chloroplast and mitochondria is the initial source of energy. chloroplasts obtain their energy from sunlight whereas mitochondria obtain theirs from organic molecules.

A nerve impulse is an electric charge running across a neuron. Explain why the stimulation supports this explanation
Softa [21]

Plato answer:

Stimulation of a neuron causes a change in the charge inside the cell from negative to positive. This change is caused by ions, which are atoms with an electrical charge, moving across the cell. This change within the cell is consistent with the definition of an electric charge.

Please help I don’t understand this!!! I’ll mark you as brainliest if correct.
Anettt [7]

Answer:

Aa

Explanation:

In Punnett Square, you are bringing the letters on the top to the numbered squares, if that makes sense. It is to predict the genotype of offspring.

So square 1, on the left is A, and on the top is A, so it would be AA.

For square 2, on the left is a, and on the top is A, so it would be Aa.

For square 3, on the left is A, and on the top is A, so it is AA.

Square 4, your question, has a on the left, and A on the top, so it is Aa.

Hope it makes sense. You should probably watch a Punnett Square tutorial online or something for a full and more general explanation.

Consider the regulation of galactose metabolism through GAL4. Which of the following would result from a mutation that allowed G
evablogger [386]

Answer: Option C.

GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.

Explanation:

Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation
