Which type of cell has no nucleus?
Prokaryotic
How do carbohydrates and lipids differ in how they store energy?
Carbohydrates= quick, energy
Lipids= energy storage
Enzymes speed up chemical __________ by ____________ activation energy.
Reactions, lowering
What is the cell membrane mostly made of?
Phospholipids
Photosynthesis happens in the __________.
chloroplast
Give one example of a prokaryotic organism.
Bacteria or archaea
Which biomolecule stores and transmits genetic information?
Nucleic Acids
What is the active site of an enzyme?
The place where the substrate binds
What does it mean that the cell membrane is "semi permeable”?
only some things can enter/leave the cell
This process only happens in plants
photosynthesis
What organelle is present in both prokaryotes and eukaryotes?
Ribosomes
Who killed the food critic and how did we come to that conclusion
Luisa- The test tested positive for complex carbs and lipids which are heavily represented in Luisa pesto pasta.
Enzymes are what type of biomolecule?
proteins
What is the name of the model used to show the different structures of the cell membrane
Fluid mosaic model
The main energy molecule made in cellular respiration is __________.
ATP
Which type of cell is generally larger and more complex?
Eukaryotic
What is the monomer of proteins?
Amino Acids
How does temperature affect enzyme activity?
It increases activity up to an optimum point, then denatures the enzyme if too hot
Give me two examples on how our body maintain homeostasis
Shivering, sweating, pupils dilating, using the restroom, insulin
name all of the components and structure of the cell membrane
lipid bilayer
proteins
carbohydrate chain
phosopholipids
transport proteins
Two students list characteristics of an organism:
• has cytoplasm
• has DNA in a nucleus
• has ribosomes
• has a cell wall
Based on the list of characteristics, Student A claims that the organism is prokaryotic, while Student B claims that the organism is eukaryotic. Identify which student is correct AND why that student is correct .
Student B is correct because eukaryotic organisms have DNA stored within a nucleus, while prokaryotic organisms do not.
A student eats a cheeseburger with a bun, meat, and cheese. Identify the main biomolecule type in each component (bun, meat, cheese) and explain the function of that biomolecule in the body.
Bun → Carbohydrates → provide quick energy.
Meat → Proteins → build and repair tissues, enzymes.
Cheese → Lipids → long-term energy storage and cell membranes.
Explain why enzymes are considered “specific.”
Each enzyme only works with one type of substrate due to its unique active site shape
How does the cell membrane help maintain homeostasis?
By regulating what enters in and out
Give me the chemical equation for photosynthesis and cell respiration
photo= sunlight + H2o + CO2 --------> O2 + C6H12O6
Cellular = O2 + C6H12O6 -------------> H2O + CO2 + ATP
