Biology pre test quiz thing

How is heat involved in the process of photosynthesis?

• The plant doesnt take in the heat and the results in no energy

• The plants take in the heat and use it to make energy

What is feedback inhabitation

• cellular control mechanism in which an enzyme’s activity is inhibited by the enzyme’s end product. This mechanism allows cells to regulate how much of an enzyme’s end product is produced.

• celluar non control mechanism

Which macromolecule gives the most energy?

• Carbohydrate

• Ribosomes

• Cytoplasm

Where is the krebs cycle in cellular respiration?

• Glycolysis transforms into the krebs cycle

• Glycolysis+ pyruvic acid transform into the krebs cycle

What are the different parts of cellular respiration and describe them.

• Glycolysis is glucose + pyruvic -> Krebs Cycle

  -> after that chemical energy transfered to the electron transport system

• Glycolysis is glucose + pyruvic

  -> after that chemical energy transfered to the electron transport system

What are the different parts of photosynthesis?

• Light shines on the plant, while carbon dioxide goes into the plant also, and carbohydrates on the leaves, and oxygen regulating out with water going into the roots.

• Light does not shines on the plant, while carbon dioxide does not go into the plant also, and carbohydrates on the leaves, and oxygen regulating out with water going into the roots.

What is the chemical reaction for cellular respiration?

• Carbon dioxide + Water Glucose (sugar) + Oxygen CO2 + H2O C6H12O6 + 6O2 Cellular

• Carbon dioxide + Glucose (sugar) + Oxygen CO2 + 6O2 Cellular

Describe the reactants and products of cellular respiration

• Oxygen and glucose represent the reactants, while carbon dioxide, water, and energy represent the products.

• Oxygen and glucose represent the products, while carbon dioxide, water, and energy represent the reactants.

What is the purpose of breathing respiration and cellular respiration in the body?

• Both help your body take in oxygen and keep you alive.

• Both help your body breath out carbon dioxide

Is cellular respiration more or less efficient than a gasoline car engine?

• Car engines convert/ capture about 34% of the energy and Cells convert/ capture only 25% of the energy.

• Cells capture about 34% of the energy and car engines convert only 25% of the energy.
