What is the sum of all the chemical reactions in the body?

All the chemical processes which sustain life. (all cells) Sum of all the chemical reactions that take place in the body, consisting of anabolism and catabolism. Cellular metabolism refers specifically to the chemical reactions within cells.

What is the sum total of all chemical reactions in an organism?

5. A. Living organisms carry out manyMetabolism different chemical reactions in order to obtain energy to run the processes of life. B. Metabolism is the sum of all chemical reactions carried out by an organism. C. Almost all the energy used by organisms is captured from sunlight.

Is the sum of all chemical reactions that occur in living cells?

Metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.

What is a condition associated with too much body fat?

Excess body fat places you at high risk for heart disease, hypertension, stroke, diabetes, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems and certain cancers, especially of the breast and endometrium (uterus). Obesity is expensive, too.

What are the four major elements in the chemicals that comprise the human body?

Anatomy&PhysiologyQuestionAnswerWhat are the four major elements found in the chemicals that comprise the human body?Carbon, hydrogen, oxygen and nitrogenThis refers to a weighted average of the atomic weights of all naturally occurring isotopes of an element?Atomic mass

What accounts for 60 to 80 percent of the body’s weight?

Water accounts for 60 to 80 percent of body weight It is the single most.

What is known as the brain of a cell because it controls the activities of the cell?

Explanation: The nucleus is called the “brain” of the cell because it holds the information needed to conduct most of the cell’s functions.

What part of an enzyme attaches to the substrate of a chemical reaction?

Enzyme Active Site and Substrate Specificity. Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.

What is an example of the basic life process called growth?

The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion. All of these processes are interrelated.

Which body fluid fills the narrow spaces between cells and tissues?

24 cards ⋅ Created by sarenandThis is the study of the function of body structuresPhysiologyThe composition of this body fluid, which fills the narrow spaces between cells and tissues, directly affects the proper functioning of cells.Interstitial Fluid

Are enzymes needed for metabolism?

Conclusion. The management of biochemical reactions with enzymes is an important part of cellular maintenance. Enzymatic activity allows a cell to respond to changing environmental demands and regulate its metabolic pathways, both of which are essential to cell survival.

What is the study of the functions of each body part?

Anatomy is the study of the structure and relationship between body parts. Physiology is the study of the function of body parts and the body as a whole.

Why is the study of biochemistry important?

It is a laboratory based science that brings together biology and chemistry. By using chemical knowledge and techniques, biochemists can understand and solve biological problems. Because of its breadth, biochemistry is very important and advances in this field of science over the past 100 years have been staggering.

Why is metabolism important to the body?

Importance of metabolism. Metabolism is the biochemical process of combining nutrients with oxygen to release the energy your our bodies need to function. Your resting metabolic rate (RMR) is the number of calories your body burns to maintain vital body functions such as heart rate, brain function and breathing.

What is the order of increasing levels of organization?

The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Which plane divides the body into the right and left halves?

The median plane is a vertical plane that divides the body into equal right and left halves, and any vertical plane that is parallel to the median plane is known as the sagittal plane. The coronal plane is a plane that separates the body into anterior and posterior parts and is sometimes known as the ‘frontal plane.’

Which directional term means farther from the midline of the body?

Preview FlashcardsFrontBackdorsalanatomical term meaning toward back of bodyinferioranatomical term meaning below or closer to the feet; also called caudallaterala directional term meaning farther away from the midline of the body

What is the most abundant element in the human body?

Almost 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.

What is the term for the bond that joins amino acids together to form proteins?

Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.

Is the sum of all chemical reactions that occur in living cells?

Metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.

What does homeostasis maintain in the body?

Humans’ internal body temperature is a great example of homeostasis. The body can control temperature by making or releasing heat. Glucose is a type of sugar that is found in the bloodstream, but the body must maintain proper glucose levels to ensure that a person remains healthy.
