A Level Biology Edexcel B Exam Questions With 100% Verified Answers Features and function of the Nucleus - answer- Present in all eukaryotic cells - Surrounded by double membrane (nueclear envelope) - Membrane contains nuclear pores to allow movement of mRNA and ribosomes out of nucleus, and enzymes into nucleus - Stores genetic material as chromatin - nucleolus (site of ribosome production) Where is the site of ribosome production? - answerNucleolus Features and Function of Rough Endop...

Structure of Nucleus. - Answer 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes. Function of Nucl...

MCAT: Cell BiologyCell Theory - correct answer 1) All living things are made of cells 2) Cell is the basic functional unit of life 3) Cells are formed from other cells 4) Cells contain DNA (genetic information) Are viruses living organisms? - correct answer No. They dont contain DNA (they have RNA), and they are not able to reproduce on their own (violates 3 and 4 of cell theory) Eukaryotic cells vs Prokaryotic cells - correct answer Eu: Nucleus. Pro: No nucleus Nucleus - correct ans...

What part of the cell contains the centrioles and the centrosomes? permuclear cytoplasm What is the function of the endocytic vesicle? moves large particles, fluid, or molecules What structure synthesizes protein for use inside cell? free ribosome The nuclear envelope has a phospholipid bilayer. True What structure regulates the passage of material between the cytoplasm and nucleus? nuclear pore What is the function of the nucleolus? ribosomal RNA synthes...

Difference between prokaryotic cells and eukaryote cells: correct answersEukaryotes have internal-membrane bound organells Prokaryote cells correct answersUnicellular organisms that don't have nuclei Eukaryotic cells correct answersOrganisms whose cells contain their genetic information inside the nucleus Which of the following structural features of phospholipid molecules affect their ability to assemble into cell membranes? correct answersPhosolipids have both hydrophonic and hydroph...

Cells - Basic unit of life Tissues - Cambos of cells with common function Several tissues together - Organ Organs working cooperatively - Organ system The whole shebang, all the organ system working together - Organism Cells have 4 common components - Plasma Membrane (fluid mosaic, Barrier, intergral proteins are embedded), Cytoplasm, DNA (genetic material of cells), Ribosomes (RNA + protein used for protein synthesis) What is not a common component for Cells - Cell wall Two types of ce...

Phospholipid bilayers are NOT stabilised by: a. van der Walls forces b. covalent bonds c. hydrogen bonds d. ionic bonds e. hydrophobic interactions - Answer-b. covalent bonds A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane, or both are exposed exclusively on...
