Bio
What are the four major biomolecules discussed in class?
Proteins, carbohydrates, lipids, and nucleic acids.
How do carbohydrates function differently in humans compared to plants?
In humans, they provide immediate energy.
In plants, they provide energy and also structural support (cellulose).
Why is cellulose important for plants but not useful for human digestion?
Cellulose provides structure for plant cell walls, but humans lack the enzymes to break its strong bonds and it passes through their digestive system without nutritional value.
What is a producer and give an example.
Produce makes its own food.
Plant is an example.
What is the process that is needed to move the water from the soil into the roots?
What are proteins made of?
Amino acids.
Why might plants store energy as starch instead of glucose?
Starch is a more stable, compact storage form that does not affect cell balance as much as free glucose.
How do proteins affect homeostasis in the human body?
Proteins regulate processes
What is a consumer and give an example?
A consumer has to eat other things to get the nutrition it needs.
Human is an example
The oxygen leaves the chloroplast using what process?
Diffusion
What is the main function of carbohydrates in humans?
They provide the primary source of energy.
What can you infer about why lipids are important for survival in both plants and animals?
They store long-term energy, protect structures, and help maintain cell membranes, which are essential for life.
How do lipids affect homeostasis in the human body?
Lipids store energy and form membranes
What does xylem do for the plant?
Xylem transports water UP from the roots, through the stem and to the leaves.
What is the chemical formula for glucose?
C6H12O6
What role do lipids play in protecting organs?
They cushion and protect vital organs.
Compare the role of proteins in humans and plants.
In both, proteins support structure and act as enzymes.
In humans, they also support muscles and immune function.
In plants, they help with photosynthesis and cell structure.
How do carbohydrates affect homeostasis in the human body?
Carbohydrates provide energy
What does phloem do for the plant?
The phloem moves nutrients DOWN through the plant to where it is needed.
What chemical test shows if lipids are present in a food sample: Benedicts, Iodine, Sudan Red, Biuret?
Sudan Red
Why are proteins important for both structure and function in organisms?
They form structures (muscles, cells) and perform functions like enzymes, transport, and immune responses.
How do carbohydrates and lipids work together to provide energy in the human body?
Carbohydrates provide quick energy, while lipids store long-term energy for later use.
Which biomolecule is most essential for life? Why?
Proteins, because they perform many roles such as making enzymes, creating structure, and transport.
How does plant carbohydrate production impact the food chain?
Plants produce glucose through photosynthesis, forming the base of the food chain and supplying energy to other organisms.
What chemical test shows if simple sugars are present in a food sample: Benedicts, Iodine, Sudan Red, Biuret?
Benedicts
