This Exam contains:

-Guarantee passing score -31 Questions and Answers -format set of multiple-choice -Expert- Explanation

Question 1: What organelle is responsible to breaking polysaccharides in to

monosaccharides?

Answer:

Lysosome Question 2: A scientist determines a means to extract all ADP from a cell. Why will this kill the cell?

Answer:

With no ADP, the cell can't make ATP in which to store the energy, so the cell could not use the energy produced.

Question 3: Name the organelles that play a role in biosynthesis.

Answer:

Ribosome, Smooth ER & Rough ER, Golgi Body, Chloroplast, Leucoplast, Nucleus, Secretion Vesicle

Question 4: How does a plant cell fight osmosis in a hypotonic solution?

Answer:

The cell has a central vacuole that expands as the cell absorbs water. This causes turgor pressure in the cell, which counteracts osmosis.

Question 5: If a cell's mitochondria stop working, can it perform any cellular respiration?

Answer:

Yes, some, but only glycolysis, which occurs in the cytoplasm Question 6: Which provides more energy per molecule of glucose: respiration in aerobic conditions or respiration in anaerobic conditions?

Answer:

Aerobic conditions Question 7: If a cell has no oxygen, what stage of aerobic cellular respiration can still run? How many ATPs can it make from a molecule of glucose?

Answer:

The cell can only run glycolysis, which can only make two ATPs per molecule of glucose.

Question 8: What is ATP's purpose in the cell?

Answer:

Supplies a package for the energy produced in cellular respiration in order to release the energy gently, thus preventing cell destruction.

Question 9: What is the difference between a phospholipid and a regular lipid?

Answer:

A phospholipid has two fatty acid molecules and a small molecule with a phosphate group, whereas a normal lipid just has 3 fatty acid molecules.Question 10: What helps the cell hold its shape if it does not have a cell wall?

Answer:

Cytoskeleton and endoplasmic reticulum Question 11: Before a polysaccharide can be used in cellular respiration in an animal cell, to what organelle must it be sent?

Answer:

To the lysosome to be broken down into monosaccharides

Question 12: What is the role of the nucleus in biosynthesis?

Answer:

Participates in the production of protein through the DNA that it contains

Question 13: What organelles or parts of the cell are involved in secretion?

Answer:

Golgi body, Secretion vesicle, Plasma Membrane, Cytoplasm

Question 14: What organelle does rough ER have?

Answer:

Ribosome

Question 15: What is the role of the Leucoplast in biosynthesis?

Answer:

Stores starches or oils

Question 16: What are the roles of the smooth ER and rough ER in biosynthesis?

Answer:

Make molecules such as polysaccharides and lipids

Question 17: What lies between the cell walls of a plant's cells?

Answer:

Middle lamella

Question 18: What is the role of the ribosome in biosynthesis?

Answer:

Makes proteins

Question 19: What is the role of the secretion vesicle in biosynthesis?

Answer:

Move products of biosynthesis to plasma membrane for secretion

Question 20: What are the eleven major tasks cells must perform?

Answer:

Absorption, Biosynthesis, Digestion, Egestion, Excretion, Homeostasis, Irritability, Movement, Reproduction, Respiration, Secretion,

Question 21: Which stage in cellular respiration produces the most energy?

Answer:

Electron transport system

Question 22: What is the role of the Golgi body in biosynthesis?

Answer:

Packages products of biosynthesis

Question 23: What parts of the cell deal with cellular movement?

Answer:

Cytoplasm, Smooth ER, Rough ER, Golgi body, Secretion Vesicles, Waste Vacuoles, Centrioles, Cytoskeleton, Plasma Membrane

Question 24: If a cell dies by implosion, what kind of solution was it in?

Answer:

Hypertonic solution Question 25: List the four stages of aerobic cellular respiration in the order in which they occur and give the net number of ATPs made in each step.

Answer:

Glycolysis(2), Formation of acetyl coenzyme A(0), Krebs cycle(2), Electron transport system(32)

Question 26: What makes it possible for the plasma membrane to self-assemble?

Answer:

Phospholipids have a hydrophilic end and a hydrophobic end, they always "know" how to reassemble.Question 27: A cell contains centrioles and lysosomes. Is it a plant or animal cell?

Answer:

Animal cell
