- How does water help to maintain homeostasis?
- It helps the cell function
- What does the cell wall do?
- Protects the cell and provides the structure for the cell
- What does a nucleus do?
- Protects the dna
- What is the function of carbohydrates?
- used as main source of energy also for structural purposes
- Give an example of a carbohydrate
- glucose, fructose
- Dna contains the coded instructions for making what important molecules?
- proteins
- What is a diploid cell?
- A cell with two sets of genes
- What does a ribosome do?
- Produces proteins
- How do enzymes influence chemical reactions in living systems?
- They speed up chemical reactions.
- What is the role of ATP?
- to power a variety of cell activities
- What are at least two factors that can regulate the rate of enzymatic activity?
- a cataylst and an enzyme
- What is the substance contained within the nucleus of the cell?
- dna
- Where does the majority of cellular respiration occur?
- the mitochondria
- Give an example of a nucleic acid
- Ribonucleic acid and deoxyribonucleic acid
- What is homeostasis?
- It's where everything is working right
- What is the monomer of carbs?
- monosacharides
- Which part of the cell plays the most central role in keeping homeostasis?
- The cell membrane
- what is the balanced equation of photosynethesis?
- 6CO2+6H2O-light-------> C6H12O6+6O2
- What is it called when water moves out of the cell?
- Hypertonic solution
- What does the mitochondria do?
- provides energy for cells
- What is the monomer of proteins?
- Amino acids
- What is the monomer of nucleic acids
- nucleotides
- Explain the relationship between the terms "macromolecule", "monomer" and "polymer".
- Macromolecules are formed when monomers join together to form polymers
- What does a chloroplast do?
- makes food from sunlight and stores carbs
- What does a vacuole do?
- Stores water, food, and waste
- What is the function of nucleic acids?
- Store and transmit heridatary or genetic info
- What is the function of proteins?
- reproduction and nutrition
- What do the centrioles do?
- control the spindle apparatus
- What is it called when water stays equal inside and out of the cell?
- isotonic solution
- What is it called when water moves into the cell?
- Hypotonic solution
- What does a lysosome do?
- breaks down bacteria
- What does the nucleolus do?
- Builds ribosomes
- What does the golgi body do?
- Produces, stores and transports proteins
- Give an example of a lipid
- fat,oil, wax
- What is the monomer of lipids?
- fatty acids and glycerol
- How does this structure work to maintain this equilibrium within the cell?
- It controls what eneters and leaves the cell so you can keep everything balanced
- What are the 4 organic compounds?
- Lipids, proteins, carbs and nucleic acids
- Which of the groups of organic compounds serve as a promary source of energy?
- Carbohydrates like breads
- What is the process called when it uses coded instructions in the dna molecule to assemble proteins in a very specific way?
- Dna transcription
- What is the balanced equation for cellular respiration?
- C6H12O6-----light---> 6CO2+6H20+ATP
- What is a haploid cell?
- A cell with a single set of genes
- Give an example of a protein
- hemoglobin, albumin
- What does the endoplasmic reticulum do?
- makes and modifys proteins
- What are the two types of respiration that can occur without oxygen?
- alcoholic fermantation, and lactic acid fermentation
- What is the function of lipids?
- energy storage, protection of organs, storage of vitamins and hormone production
- How does the avalibility of water and temperature affect phtosynethesis?
- If the tempeture and water are at optimal amounts then phtosynethesis will be the most effective
