All living things obtain and use energy…

How do plants convert energy from the sun into food for energy?

Trace the path of energy from the sun to glucose.

Sun–> Energy is captured in leaves by chlorophyll inside the organelle chloroplasts. –> Energy is captured by electrons and carried in ATP and NADPH. –> The high-energy electrons are used to build molecules the cell need like glucose.

What do plants need in order to undergo photosynthesis?

Photosynthesis within chloroplasts is divided into two phases:

1) Light Reactions (occurs in the thylakoid disk)

i) Electrons excited by the sun are carried by ATP and NADPH to where the next phase occurs.ii) (a) H2O

Biology 101: Circulatory, Respiratory, and Lymphatic Systems Study Guide and Review — Moosmosis

In this quick and easy biology final exam study guide, we share our notes and review the circulatory, respiratory, and lymphatic systems in the following 3 sections. From the anatomy of the heart and blood flow in the circulatory system to the breaths we take traveling through the lung and lymphatic flow.

Biology Unit 2 Study Guide: Basic Building Blocks of Life

 What are biomolecules?

 Biomolecules are large molecules made of many smaller repeating units.  Therefore they are also considered polymers because they are made of many monomers.

What helps molecules stick together?

Complete the table about types of chemical bonds.

Type of Bond

Formed When…

 

Covalent Bond

electrons are shared between atoms

 

 

 

Ionic Bond

electrons are transferred from one atom to another and the two atoms are held together by the attraction of opposite charges

 

 

Hydrogen Bond

attraction between hydrogen atom on one water molecule and oxygen atom on another water molecule – not as strong as covalent or ionic bond

 

Role of Lipids

Lipids have many roles within the cell and body and the function depends on the type of lipid.  What are the functions of the following lipids?

Type of Lipid

 CHARACTERISTICS OF LIFE

BIOLOGY is the study of living things.   To distinguish something as living, it must have all of the following characteristics of life:

  1. made of cells
  2. obtain and use materials and energy (metabolism)
  3. all reproduce
  4. maintain internal balance (homeostasis)
  5. have genetic code (DNA/RNA)
  6. respond to environment
  7. grow and develop
  8. as a group, change over time (evolve)

What is the difference between homeostasis and responding to the environment?

homeostasis is maintenance of internal conditions, not through conscious thought (ex. sweating when hot, liver storing sugar, etc.)     

response to environment is changes to the organism caused by changes in the environment (ex. plant growing because of sunlight, lizard sitting on rock to keep warm, etc.)

What is the SMALLEST unit that is still considered living?

A cell

Out of the following words, circle all those that are…

Intracellular Digestion vs. Extracellular Digestion

Moosmosis

What is the Difference Between Intracellular Digestion and Extracellular Digestion? 

In this article, we explore the definitions and difference between Intracellular and Extracellular Digestion.

Intracellular Digestion = Digestion that occurs inside our cells (literally in the cytoplasm)

Extracellular Digestion = Digestion that occurs outside our cells

Lo and behold! Welcome our holy grail – glucose! While glucose’s essence as the holy grail may be debatable, glucose undeniably serves as an essential energy source for our bodies. In order to utilize glucose as our energy, we must first digest food that contains glucose. There are two main types of digestion: intracellular and extracellular.

Our Human Digestive System: Wonderful, isn’t it? 🙂

Definitions of Intracellular Digestion and Extracellular Digestion

Let’s first dissect the ‘anatomy’ of our word “intracellular.” The prefix intra means “on the inside” or “within,” and the suffix cellular literally refers to our cells. Intracellular digestion thus means digestion that…

Nutrition: Glucose and Diabetes Type 1 vs. Type 2, Carbohydrates, Lipids, and Proteins

Nutrition: Glucose and Diabetes Type 1 vs. Type 2, Carbohydrates, Lipids, & Proteins

 Once delicious food has been digested, nutrients enter the bloodstream to reach all the cells in your body.  Your cells need glucose all the time to keep producing ATP through the process of cellular respiration.  The body is always trying to maintain a consistent sugar level in your blood – making sure it is not too high or low.  Sugar levels in the blood are controlled by two hormones released by the pancreas.

After you eat and your blood sugar level is high, insulin is released to encourage uptake of glucose into your cells and to help convert glucose to glycogen for storage in the liver.

If you haven’t eaten in a while and blood sugar level is low, glucagon is released to convert glycogen to glucose for delivery to your cells.
