What are lipids?
What function of life involves chemical transformations of food into usable cellular energy?
What is metabolism?
What biological level comes immediately after cells in the hierarchy of organization?
What are tissues?
What are the three main environmental factors that affect enzyme activity?
What are temperature, pH, and substrate concentration?
I’m made of monosaccharides and taste sweet. You burn me first for energy. What am I?
What is a carbohydrate?
Which type of carbohydrate serves as structural support in plant cell walls?
What is cellulose (a polysaccharide)?
Why is reproduction not essential for the survival of an individual, but critical for the survival of a species?
What is because individuals can live without reproducing, but species must reproduce to avoid extinction?
Which three types of plant tissues were covered in class?
What are vascular, ground, and epidermal tissues?
Explain how pepsin and amylase demonstrate that different enzymes work best at different pH levels.
What is pepsin works in acidic pH (stomach), while amylase works in neutral/slightly basic pH (mouth/small intestine)?
I’m hydrophobic, store energy long-term, and come from avocados. What am I?
What is an unsaturated lipid (fat)?
What is the specific name of the reaction that forms a glycosidic bond?
What is a condensation (or dehydration synthesis) reaction?
Which function of life describes how organisms detect and respond to stimuli?
What is response?
At what level of organization would you categorize a kidney?
What is an organ?
How does the shape of the active site relate to enzyme specificity?
What is that only substrates with complementary shape can bind, like a lock and key?
I’m a molecule made of amino acids and I fold into complex shapes to carry out specific jobs. What am I?
What is a protein?
Which biomolecule is involved in every stage of protein synthesis and can act as an enzyme?
What is RNA?
Explain why homeostasis is considered a dynamic equilibrium rather than a static state.
What is because internal conditions constantly adjust to changes, maintaining balance without being fixed?
Differentiate between a population and a community with examples.
What is a population is one species (e.g., zebras); a community includes multiple species (e.g., zebras + lions + grass)?
Describe what happens during the formation and release of an enzyme-substrate complex.
What is the enzyme binds the substrate, catalyzes the reaction, and releases the product without being changed?
I’m a twisted ladder with four kinds of nitrogen bases. Who am I?
What is DNA (a nucleic acid)?
Name the elements found in all four major biomolecules and identify the two that are exclusive to proteins and nucleic acids.
What are C, H, O (all); N (proteins and nucleic acids); P (nucleic acids only)?
Evaluate how metabolism and excretion are interdependent in maintaining cellular health.
What is metabolism generates waste that must be eliminated by excretion to prevent toxicity?
Name one abiotic and one biotic factor from an ecosystem and explain how they interact.
What is sunlight (abiotic) and plants (biotic)? Sunlight allows plants to photosynthesize.
Using enzyme graphs, explain what it means when the reaction rate plateaus despite adding more substrate.
What is all the enzyme active sites are saturated, no more substrates can be processed at once.
You need me to speed up reactions, but I’m picky and hate being overheated. What am I?
What is an enzyme?
