System Interactions
Two systems that regulate glucose?
ENDOCRINE AND DIGESTIVE SYSTEMS
Name one basic function of life.
Metabolism, growth, reproduction, response to stimuli, homeostasis
What is the chemical formula of water?
H₂O
List the correct order from smallest to largest: cell, tissue, organ, organism.
Cell → tissue → organ → organ system → organism
Name 3 examples made of monosaccharides?
Glucose, fructose, galactose, ribose, deoxyribose
How do respiratory and circulatory systems work together?
Oxygen enters blood in lungs and is transported by the blood
Which function of life allows organisms to maintain stable internal conditions?
Homeostasis
Which atom is essential for thyroxine?
Iodine (I)
The endocrine system is made of glands. To which type of tissue it belongs glands?
Epithelial tissue
Give the chemical formula for glucose.
C₆H₁₂O₆
Connect alveoli to circulation.
Alveoli allow oxygen to diffuse into capillaries
Explain how enzymes support the function of metabolism.
They speed up chemical reactions needed for metabolism
Identify the monomers that form nucleic acids.
Nucleotide
Explain how energy enters an ecosystem at the chemical level.
Through chemical bonds in glucose produced by photosynthesis
Which biomolecule contains the elements C, H, O, N?
Proteins
Explain an example of a positive feedback loop that uses both nervous and endocrine systems.
Breastfeeding, Nipple stimulation through the biting sense signal using sensory neurons to the hypothalamus, which sends a signal to the anterior pituitary, which releases oxytocin to eject milk.
Which two functions of life are directly involved when sweating during exercise?
Response to stimuli and homeostasis
Which type of bond joins amino acids together, and what is it called?
Covalent bond called a peptide bond
List the layers of tissues found in the heart.
Endocardium, myocardium, pericardium, nervous tissue, and connective tissue (cartilage)
Explain how enzymes are specific to their substrates.
Their shape fits only specific molecules (lock-and-key or induced fit)
Explain an example of a negative feedback loop that uses both nervous and endocrine systems.
Sympathetic and parasympathetic nervous systems are activated during and after an emergency, triggering Adrenaline and Noradrenaline responses.
Predict what would happen to an organism if enzymes stopped functioning properly.
Metabolism would slow or stop, disrupting all life functions
Explain why carbon can form complex biological molecules.
It forms four covalent bonds, allowing chains and rings
Compare the function of the Golgi Apparatus to the Liver. How are they similar?
Both store and distribute substances to the cell and the body, respectively.
Match the biomolecule to its function and formula:
Energy storage, enzyme activity, and genetic information
Carbohydrates/lipids → energy (C₆H₁₂O₆); proteins → enzymes (C,H,O,N); nucleic acids → genetic info (DNA/RNA: C,H,O,N,P)
