Lipids are a class of organic compounds, which suits best under the column macromolecules on the hierarchy of biological organization.
Biological organization refers to the hierarchy of composite biological systems and compositions, which illustrate life using a reductionistic method. The conventional hierarchy moves from an atom to more complex biospheres.
Each of the level in the hierarchy signifies an enhancement in the organizational complexity, with each component being mainly comprised of the previous basic unit level.
Answer:
D Flow of protons across an electrochemical gradient
Explanation:
The chloroplast adenosine triphosphate (ATP) synthase uses the electrochemical proton gradient generated by photosynthesis to produce ATP, the energy currency of all cells. Protons conducted through the membrane-embedded Fo motor drive ATP synthesis in the F1 head by rotary catalysis.
In chloroplasts, photosynthetic electron transport generates a proton gradient across the thylakoid membrane which then drives ATP synthesis via ATP synthase.
The light-induced electron transfer in photosynthesis drives protons into the thylakoid lumen. The excess protons flow out of the lumen through ATP synthase to generate ATP in the stroma.
Majority of ATP is produced by OXIDATION PHOSPHORYLATION. The generation of ATP by oxidation phosphorylation differs from the way ATP is produced during glycolysis.
Electrons are passed from one member of the transport chain to another in a series of redox reactions. Energy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis.
Answer:
Lateral Hypothalamus
Explanation:
According to the hunger researchers' initial assumption lateral hypothalamus is that part of the brain which regulates intake of food and metabolical activities like metabolical regulation of peptides like the orexins melanin-concentrating hormone. It is that part of the brain that plays a key role in the ingestive behavior regulation.
The lateral hypothalamus system initiates physical and cognitive processes like it promotes arousal and feeding behavior, metabolism, regulates body temperature, BP, etc. and when stimulated it results in the feeding behaviour in animals as they begin to eat.
