Hi i hope you can answer this question and possibly link me or explaining me the reason of choosing it.
i know there are many questions but these are the question i could not understand as this is not my link degree. PLease help me.

(b) The nucleus is surrounded by an envelope.
(c) The endoplasmic reticulum may be rough or smooth.
(d) The nuclear envelope contains pores.
(e) The chloroplast is surrounded by an envelope
--------------------------------------
Which of the following statements is UNTRUE?
(a) Lysosomes are concerned with intracellular digestion.
(b) A nucleus is found in all eukaryotic cells.
(c) The rough endoplasmic reticulum provides a large surface area for the attachment of nucleosomes.
(d) The mitochondrion is surrounded by an envelope.
(e) The lipids of the plasma membrane form a bilayer
-----------------------------------------
Which of the following functions in secretion:
(a) Mitochondria
(b) Chloroplasts
(c) Nucleus
(d) Microbodies
(e) Golgi apparatus
---------------------------------------------
Which of the following statements is INCORRECT?
(a) Enzymes do not affect the change in free energy (G) of a reaction.
(b) Enzymes do not affect the equilibrium position (that is, K) of a reaction.
(c) Enzymes reduce the activation energy (EA) of a reaction.

hi
Which of the following statements is UNTRUE?
(a) The plasma membrane is a bilayer of lipid molecules. yes
(b) The nucleus is surrounded by an envelope. yes
(c) The endoplasmic reticulum may be rough or smooth.yes
(d) The nuclear envelope contains pores.yes
(e) The chloroplast is surrounded by an envelope no, consist of bilayer

Which of the following statements is UNTRUE?
(a) Lysosomes are concerned with intracellular digestion.
(b) A nucleus is found in all eukaryotic cells.
(c) The rough endoplasmic reticulum provides a large surface area for the attachment of nucleosomes.NO untrue, there are no nucleosomes in ER only rybosomes
(d) The mitochondrion is surrounded by an envelope.
(e) The lipids of the plasma membrane form a bilayer
-----------------------------------------
Which of the following functions in secretion:
(a) Mitochondria
(b) Chloroplasts
(c) Nucleus
(d) Microbodies
(e) Golgi apparatus/yes Secretes proteins and other substances out of the cell via vesicules
---------------------------------------------
Which of the following statements is INCORRECT?
(a) Enzymes do not affect the change in free energy (G) of a reaction.
(b) Enzymes do not affect the equilibrium position (that is, K) of a reaction.?not sure i think this one, they do affect equilibrium, make sure what K is
(c) Enzymes reduce the activation energy (EA) of a reaction.
(d) Enzymes are found in all types of biological cells.
(e) None of the above.
