Cellular Respiration
100 — What organelle is called the "powerhouse of the cell" where most cellular respiration occurs?
100 — Mitochondrion (mitochondria)
100 — Which organelle captures light energy for photosynthesis?
100 — Chloroplast
100 — Identify an element within the formula is glucose.
Carbon , Hydrogen , Oxygen
100 — What small structures inside cells carry out cellular respiration?
100 — Mitochondria
100 — What term describes the rate at which producers in an area produce biomass?
100 — Net Primary Productivity (primary productivity)
200 — In which part of the cell does glycolysis occur?
200 — Cytoplasm
200 — List the three main inputs to photosynthesis
200 — Sunlight (energy), carbon dioxide (CO₂), and water (H₂O)
200 — From the respiration chemical equation, how many oxygen molecules are in the products? Give the numeric coefficient and formula.
200 — carbon dioxide (6CO₂), and water (6H₂O)
12 + 6 = 18 oxygen
200 — Which organelle is unique to producers and captures sunlight?
200 — Chloroplasts
200 — Give one advantage of algal biofuel .
200 — Example: Algae grow quickly and are renewable (also: can be grown in non-drinking water; can use CO₂ emissions)
300 — Name two products of cellular respiration besides energy.
300 — Water (H₂O) and carbon dioxide (CO₂) — or energy (ATP) and water/CO₂
300 — Write the balanced chemical equation for photosynthesis using the formulas from the documents.
6CO2+6H2O+sunlight→C6H12O6+6O2
300 — Question: Count the atoms — How many hydrogen atoms are in glucose?
H= 12 C6H12O6
300 — The inner mitochondrial membrane has many folds. What is the purpose of these folds?
300 — The folds increase total surface area, allowing more space for chemical reactions (more ATP production).
300 — Explain how glucose produced by photosynthesis can be stored in plants (name the storage molecule) Hint - Can be eaten
300 — As starch (plants store excess glucose as starch)
400 — Describe in one sentence why cellular respiration needs oxygen (use the workbook hint: think "fire").
400 — Oxygen is required as the final electron acceptor in the reactions that release a large amount of energy (analogy: like oxygen that helps a fire keep burning), so without oxygen the high-energy-yield stages cannot run efficiently.
400 — Explain how the products of photosynthesis are used by a plant (give two different fates for sugar).
400 — Sugars can be used immediately for life processes (respiration) or stored (for example, as starch in roots or stems); sugars also build other molecules (e.g., cellulose).
400 — Explain the conservation of matter.
Matter is neither created nor destroyed; it can only transform and transport.
400 — Name the element required for the generation of energy or ATP within the mitochondria?
Oxygen
400 — List two biological fates of proteins when absorbed.
Protein can be utilized within cell growth, cell repair, and cell transport
500 — The mitochondrion produces most of the cell's ATP. Name the stage before the mitochondrion stage?
Glycolysis
500 — Using evidence from the diagrams, explain how photosynthesis and cellular respiration form a cycle between chloroplasts and mitochondria (one short paragraph).
500 — Photosynthesis in chloroplasts produces sugar and oxygen; mitochondria use sugar and oxygen to produce energy (ATP), water, and carbon dioxide; the carbon dioxide and water can then be reused by chloroplasts—forming a cycle.
500 — Complete this reaction: water + carbon dioxide →→ carbonic acid.
Write the chemical formulas in order using the correct formulas from the documents.
H20 + CO2 >>> H2CO3
500 — Describe how the cytoplasm and mitochondrion participate in the full process of cellular respiration (include the stages that occur in each location).
500 — Glycolysis occurs in the cytoplasm where glucose is broken into smaller molecules (releasing a small amount of energy). The smaller molecules move into the mitochondrion where the Krebs cycle and electron transport produce a large amount of ATP.
500 — Use primary productivity idea and cellular processes: Explain in two or three sentences why a region with higher primary productivity supports more consumers.
500 — Regions with higher primary productivity produce more plant biomass (more sugar and energy stored in producers). This greater energy base supports larger populations and more trophic levels of consumers because more food is available.
