Chemical reactions; food; broken; rearranged
___ use energy from ___ to make ___ (food) from ___ ___ and ___.
Plants; light; sugars; carbon dioxide; water
____ and other ____ from the soil are not ____ (they don't provide energy), but they are needed for plants to make complex molecules from the they make.
Minerals; nutrients; food; sugar
____ is transferred from one organism in an ecosystem to another as the organisms interact with each other for food.
the ____ that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem.
____ can change from one form to another in living things. ____ get energy from oxidizing their food, releasing some of its energy as heat. Almost all food energy comes originally from sunlight.
The term ____ is commonly known as whatever nutrients plants and animals must take in if they are to grow and survive.
In ____ terms, food refers only to those substances, such as carbohydrates, proteins, and lipids, from which organisms derive the energy they need
to ____ and ____ and the material of which they are made.
scientific; grow; operate
A ____ combined with ____ in the overall general health of the body.
balanced diet; regular exercise aid
Humans require ___ to function.
The amount of energy required to maintain minimum essential life functions is called ____, or ____.
basal metabolic rate; BMR
Humans obtain the energy required to carry out basic life processes from the ____ they consume. Food energy is measured in ____.
For the body to use ____ (proteins, lipids, carbohydrates) for energy and building materials, the food must first be digested into molecules that are ____ and ____ to cells.
Food; absorbed; transported
What are the products of photosynthesis?
Light (energy) + Co2 + H2O = C6H12O6 + O2
What happens during photosynthesis?
Light energy is absorbed by chlorophyll, then converted to sugars and oxygen.
How does photosynthesis benefit heterotrophs?
It creates the food they eat.
What happens during cellular respiration?
Oxygen and glucose broken down.
The stage of respiration that releases most of the energy in glucose occurs in the ____?
How are photosynthesis and cellular respiration related?
Photosynthesis and cellular respiration have opposite equations.
Together, respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere ____?
The energy-releasing process that does not require oxygen is called ____?
Under what conditions is lactic acid fermentation most likely to occur?
When oxygen is used up faster than it is replaced. An example is a fast run.
What captures sunlight during photosynthesis?
How does carbon dioxide enter plants?
Through small openings on the undersides of leaves called stoma.
Where (in humans) does alcoholic fermentation occur?
In yeast cells (not in body). Lactic acids occurs in the body.
The amount of energy required to raise the temperature of one gram of water by one Celsius degree is called a ____?
A calorie is a unit used to measure ____?
The energy our body needs comes from ____?
Which nutrients are made up of amino acids?
Which nutrients is needed in order for all body processes to take place?
Name one role of fats?
They form part of the cell membranes and plasma membranes
What digestive organ releases enzymes that help break down starches, proteins, and fats in the small intestines?
What substances are produced during respiration?
Carbon dioxide, water, and ATP.
What term do scientists use to describe the chemical process in which oxygen and glucose react to release energy inside body cells?
A change from one form of energy to another is called ____?
When an animal eats food, the food and other nutrients must enter each cell in the animals body so the cells can carry out their functions. How do the food molecules and nutrients enter the cell?
Through the plasma membrane
How do the cells of the body respond when a person, over time, has a poor diet and little exercise?
A poor diet and little exercise reduces the rate of respiration cells die off.
As you exercise, why does respiration rate increase?
More oxygen is needed in order to utilize energy needed to exercise.
ATP known as ____ is created during the process of ____.
Andosine Triosphate; respiration
A person's BRM is a measure of ____.
Rate at which a person's body burns energy at rest.
The energy stored in ATP provides a means by which all cells are able to _____.
Growth, repair, and development.
Plant food sources included sugars made out of ____ and ____.
Carbon dioxide; water
The set of chemical reactions involved involved in storing fuel (food) molecules and converting fuel (food) molecules into energy is known as____.
Why is a vital process for all life forms?
Metabolism gets fuel to power cells.
How does energy enhances/pass from plants to other organisms?
The food chain. Primary producers- Primary consumers- Secondary-
consumers- Tertiary consumers
How does energy change from one form to another in living things?
Light energy- chemical energy (plant)- chemical energy (animal)-
Describe what enzymes do for proteins, fats, and carbohydrates.
Proteins, fats, and carbohydrates need enzymes to break them down.
What is the role of the endocrine system in the process of metabolism?
An overactive thyroid produces too much of the thyroid hormones and causes the body's metabolic rate to crease. An under-active thyroid does not produce enough of the thyroid hormone, which causes the metabolic rate to slow.
What is BMR, and what does it do?
Basal Metabolic Rate burns energy while it rests.
What factors BMR?
Inheritance, exercise, health, and weight loss.
What are the results of blocked or defective metabolism?
Not enough energy, disease, diabetes.
