Question:
Bulk transport across the plasma membrane occurs by exocytosis and endocytosis.
Answer:
• Small molecules and water enter or leave the cell through the lipid bilayer or via transport
proteins.• Large molecules, such as polysaccharides and proteins, cross the membrane in bulk via
vesicles.• Bulk transport requires energy
Question:
Signal Reception:.
Answer:
- Receptors are glycoproteins that bind with specific signaling molecules.- Many hydrophilic
molecular signals bind to receptors on the surface of the target cell and do not actually enter the cell.
Hydrophobic molecules move through the plasma membrane and bind with intracellular receptors.-
A ligand binds to a specific receptor and triggers a biological response. Only the signaling molecule
that fits the shape of a specific receptor can trigger a response in a cell.- The signals a cell responds
to depends on its receptors. Different cell types produce different receptors. A cell may synthesize
many different kinds of receptors.
Question:
What is photorespiration?
Answer:
When the enzyme rubisco binds O■ during the Calvin Cycle.
Question:
Prokaryotic cells have:.
,Answer:
• No nucleus.• DNA in an unbound region called the nucleoid.• No membrane-bound organelles.•
Cytoplasm bound by the plasma membrane
Question:
Enzyme-Linked (tyrosine kinase) Receptors (RTKs).
Answer:
are membrane receptor enzymes that attach phosphates to amino acid tyrosine. A receptor tyrosine
kinase can trigger multiple signal transduction pathways at once. Abnormal functioning of RTKs is
associated with many types of cancers.
Question:
What occurs during light-independent reactions of photosynthesis?
Answer:
Carbon dioxide is converted into sugars.
Question:
Mitochondria.
Answer:
are the sites of cellular respiration, a metabolic process that uses oxygen to generate ATP.
Question:
What is the function of tRNA during translation?
Answer:
Brings amino acids to the ribosomes.
Question:
,What determines the difference between amino acids?
Answer:
R or variable groups.
Question:
What is the definition of mutation?
Answer:
A change in the DNA sequence.
Question:
Where does glycolysis occur in a cell?
Answer:
Cytosol or cytoplasm.
Question:
- During endocrine signaling, (Signal transmission).
Answer:
messenger molecules (hormones) secreted by endocrine glands reach their target cells through the
bloodstream.
Question:
The nucleus.
Answer:
contains most of the cell's genes and is usually the most conspicuous organelle
Question:
The Golgi apparatus.
, Answer:
consists of flattened membranous sacs called cisternae.
Question:
Hydrolytic enzymes and lysosomal membranes.
Answer:
are made by rough ER and then transferred to the Golgi apparatus for further processing.
Question:
During which stage of meiosis do homologous pairs separate?
Answer:
Anaphase I.
Question:
- Most water-soluble signal molecules bind to specific sites on receptor proteins that span the
plasma membrane. There are three main types of membrane receptors:.
Answer:
•ion channel-linked,•G-protein linked (coupled), and•enzyme-linked receptors
Question:
There are three types of endocytosis.
Answer:
• Phagocytosis ("cellular eating"): In phagocytosis a cell engulfs a particle in a vacuole. The vacuole
fuses with a lysosome to digest the particle.• Pinocytosis ("cellular drinking"): In pinocytosis,
molecules dissolved in droplets are taken up when extracellular fluid is "gulped" into tiny vesicles•
Receptor-mediated endocytosis: In receptor-mediated endocytosis, binding of ligands to receptors
triggers vesicle formation. A ligand is any molecule that binds specifically to a receptor site of
another molecule.
