Question 1 is nucleolus and other chromatins (chromosomes), nuclear bodies, nuclear matrix, nucleoplasm, and nuclear envelope. Question 2 is Lysosomes are membrane-bound organelles found in every eukaryotic cell. They are widely known as terminal catabolic stations that rid cells of waste products and scavenge metabolic building blocks that sustain essential biosynthetic reactions during starvation.

Which stage of cellular respiration produces the most atp?
ankoles [38]

Answer:

Electron transport Chain (Oxidative phosphorylation)

Explanation:

Cellular respiration can be defined as the process that involves the breakdown of glucose molecules into CO2 and H2O to generate energy inform of Adenosine Triphosphate (ATP).  Also, cellular respiration usually takes place in the cells of an organism by converting biochemical energy present nutrients into Adenosine Triphosphate. Furthermore, it takes place in three stages which includes: glycolysis, TCA cycle and Electron transport (Oxidative phosphorylation). Thus, oxidative phosphorylation is the final stage of aerobic cellular respiration that produces maximum ATPs.

What is the role of the ion channel (in easy words)
ArbitrLikvidat [17]

Answer:

Ion channels are specialized proteins in the plasma membrane that provide a passageway through which charged ions can cross the plasma membrane down their electrochemical gradient.

Explanation:

Ion channels are molecular machines that serve as principal integrating and regulatory devices for controlling cellular excitability. Different types of ion channels have been described: channels that respond to mechanical, electrical (voltage-dependent ion channels), or chemical stimuli (ligand-gated ion channels); ion channels that are controlled by phosphorylation/dephosphorylation mechanisms; and ion channels that are dependent on G proteins. Most ion channels are of the voltage-dependent type and consist mainly of sodium (Na+), potassium (K+), and calcium (Ca2+) channels. Drugs can affect ion channel function directly by binding to the channel protein and altering its function or indirectly through G proteins and other intermediates. Lidocaine is a good example of a drug that directly affects voltage-gated Na+ channels by blocking the channel and thus Na+ entry into the cell.

Thanks! Have a great day!
