I. Chemical compounds in cells are made of elements or combinations of elements. Elements cannot be broken down further, while compounds contain two or more elements chemically bonded together. There are organic and inorganic compounds, with organic compounds containing carbon and usually associated with living things. The four main groups of organic compounds are carbohydrates, lipids, proteins, and nucleic acids, each made up of certain elements and serving important cellular functions.

The document discusses the chemical composition of cells. Cells are made up of elements like carbon, hydrogen, oxygen, sulfur, nitrogen, and phosphorus. These elements form large, complex molecules like amino acids, which are the building blocks of proteins. Amino acids join together through peptide bonds to form polypeptide chains. Polypeptides then fold into primary, secondary, tertiary, and quaternary protein structures that carry out essential functions in cells. There are 20 common amino acids, some of which are essential and must be obtained through diet.1 molecules of life

The four major inorganic substances are water, oxygen, carbon dioxide, and salts. The four main organic macromolecules that make up living things are carbohydrates, lipids, proteins, and nucleic acids. Each macromolecule has specific structures and functions, such as carbohydrates providing energy and lipids storing energy.Lesson 5-Chemical And Biological Foundations of Life.pptx

Organic molecules in living systems include macromolecules made of polymers of smaller subunits. The four main types of macromolecules are lipids, proteins, carbohydrates, and nucleic acids. Lipids are made of fatty acids and glycerol and function in energy storage and cell membranes. Proteins consist of amino acid monomers and have roles as enzymes, membrane components, and tissues. Carbohydrates polymerize into sugars like starch from monosaccharides and serve as energy sources. Nucleic acids like DNA and RNA store genetic information as polymers of nucleotides. These macromolecules are broken down into their subunits during digestion and rebuilt in cells.Water and life substances

The document discusses the importance of water and its properties. Water is a polar molecule with unequal charge distribution, allowing it to dissolve many ionic and polar compounds. Water molecules are also attracted to each other through hydrogen bonding. This property allows water to absorb large amounts of heat, maintaining stable conditions for organisms. The document also summarizes the key biomolecules that make up living things: carbohydrates, proteins, lipids, and nucleic acids. It describes the basic monomers, polymers, and functions of each biomolecule.More from ÓË¥M´Ç°ù¾±²¹³óÓË¥ (16)

The document discusses verb tenses in English. There are three simple tenses: present, past, and future. The present tense follows rules about adding "s" or "es" to verbs depending on their ending when the subject is singular. The past tense typically adds "ed" but has special rules for doubling consonants or dropping "e". The future tense uses the basic verb form with the helping verbs "will" or "shall".Discovering Cells Guided Note Taking Worksheet With Page Numbers

Cells were first observed in the late 1600s by Anton van Leeuwenhoek using a single-lens microscope. He discovered microscopic plants, animals, and other organisms that he called "animalcules." The cell theory, developed in the 1830s and 1840s by Schleiden, Schwann, and Virchow, established that all living things are made of one or more cells and that cells are the basic unit of structure and function in living things. Modern microscopes like electron microscopes can magnify specimens up to tens of millions of times using electromagnetic lenses or beams instead of glass lenses.Moving Cellular Materials Power Point

All cells take in nutrients and expel waste through the cell membrane. The cell membrane is selectively permeable, allowing some substances to pass through passively via diffusion, osmosis, or facilitated diffusion without using energy. Other substances require active transport using transport proteins and cellular energy to move against the concentration gradient into or out of the cell. There are two main types of active transport: endocytosis which surrounds and takes material into the cell, and exocytosis which expels material out of the cell.Cell Organelles Powr Point

Cells come in different sizes and shapes. All cells have a cell membrane which controls what enters and exits the cell, and cytoplasm which is a gel-like material. Only plants, algae, fungi and bacteria have cell walls. The nucleus is the control center of the cell and contains genetic material. Organelles like mitochondria, ribosomes, the endoplasmic reticulum and golgi bodies carry out specific functions within the cell. Mitochondria convert energy from food into a form cells can use, while ribosomes produce proteins and the endoplasmic reticulum transports materials.A D D I N G I N T E G E R S

1) A mixed number has a whole number part and a fractional part, while an improper fraction has a numerator larger than the denominator.
2) To change between mixed numbers and improper fractions, you can multiply or divide the whole number by the denominator and add or subtract the numerator.
3) When adding, subtracting, multiplying or dividing fractions, you often need a common denominator or need to use reciprocals.Cell Organelle Notes

Cells have a cell membrane that controls what enters and exits. The nucleus is the control center holding genetic material and telling the cell what to do. Organelles like mitochondria and chloroplasts have specific functions - mitochondria convert energy while chloroplasts capture sunlight to make food in plant cells. Cells are the basic units that make up higher levels of organization like tissues, organs, and systems within complex organisms.Cell Organelle Cloze Notes

The nucleus is the control center of the cell and contains DNA. It is surrounded by a membrane. Ribosomes produce proteins and may be free in the cytoplasm or attached to the endoplasmic reticulum. The endoplasmic reticulum transports molecules through a series of membranes and may be rough or smooth. Mitochondria are the powerhouses of the cell and convert energy. Vacuoles store waste and other materials. Lysosomes break down materials as the cell's waste management system. Microtubules and microfilaments make up the cytoskeleton to support the cell.Chapter 1 Study Guide

To add or subtract fractions with like denominators, add or subtract the numerators and keep the same denominators, simplifying the resulting fraction if needed. There are two types of fractions: proper fractions where the numerator is smaller than the denominator, and improper fractions where the numerator is greater than or equal to the denominator. For improper fractions, the answer must be simplified by dividing.Chemical Compounds In Cells Outline
