What is the modern theory of evolution also known as?
The modern theory of evolution is also known as the synthetic theory of evolution or the modern synthesis. It combines Darwin's theory of natural selection with genetics and other fields of biology to explain how organisms evolve over time.
What did Theodosius Dobzhansky discover?
He contributed to the modern synthesis theory; a comprehensive theory of evolution that integrated ideas from many fields.
How enzyme structure makes an enzyme very specific?
Enzymes are proteins, which are made up of amino acids. Each enzyme has a different sequence of amino acids and changing even one amino acid will mean that the tertiary structure of the enzyme will be lost and so will it's active site. As enzymes are substrate specific, only a certain substrate will bind to its active site, due to its amino acid sequence determining the shape of the active site.
Which theory explains ATP synthesis chloroplast and mitochondria?
The chemiosmotic theory explains ATP synthesis in both chloroplasts and mitochondria. This theory states that ATP is generated through the movement of protons across a membrane, creating a proton gradient that drives the synthesis of ATP by ATP synthase. In chloroplasts, this process occurs in the thylakoid membrane during photosynthesis, whereas in mitochondria, it occurs in the inner mitochondrial membrane during cellular respiration.
What are weaknesses of activation-synthesis theory?
Weaknesses of the activation-synthesis theory of dreaming include the lack of direct evidence supporting its claims, the oversimplification of the complex process of dreaming, and the inability to explain the emotional content and deeper meanings of dreams. Additionally, some critics argue that the theory fails to account for individual differences in dream content and experiences.
What theory are neurons in psychology?
activation synthesis
Which statement describes the currently accepted theory of how an enzyme and its substrate fit together?
There is an enzyme explanation whose specificity states that an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another. This is the lock and key explanation.Ê
What are the two theories that explain enzyme specificity?
The lock and key theory and the induced fit theory are two theories that explain enzyme specificity. The lock and key theory proposes that the enzyme's active site is already in the correct shape to bind the substrate, like a key fitting into a lock. The induced fit theory suggests that the active site of the enzyme can change its shape slightly to accommodate the substrate, similar to a glove molding around a hand.
What Theory that says dreaming is an unimportant by product of neural firing during sleep?
Ativation-Synthesis
What is the theory that describes how an enzyme works or bonds?
The theory of the enzyme is really quite simple-patronisingly easy really. So firstly we start off with the Lipese enzyme which breaks down fat-quite usefull really with todays growing obeseity epidemic, then we move on to carbohydrase enzyme which breaks down carbohydrate-(people which suffer from diabetes lack in this particular enzyme). Expert scientists believe that in a few years the number of enzymes in the body will rapidly increase.
What is the modern theory of evolution also known as?
The modern theory of evolution is also known as the synthetic theory of evolution or the modern synthesis. It combines Darwin's theory of natural selection with genetics and other fields of biology to explain how organisms evolve over time.
What is the name of the theory that describes how an enzyme works?
Lock and Key hypothesis
When enzyme fits into substrate at an active site?
lock and key theory
Who was George Beadle partner?
His partner's name was Edward Lawrie Tatum and together they developed the "one gene, one enzyme theory." The theory, all summarized, stated that each gene controls a particular enzyme.
Who proposed the currently accepted theory of evolution?
The theory of evolution by natural selection was proposed by Charles Robert Darwin and Alfred Russel Wallace in 1858. This is not the currently accepted theory as that was 157 years ago. Google The new synthesis, or the Neo-Darwinian synthesis for an update to the theory of evolution by natural selection.
What did Theodosius Dobzhansky discover?
He contributed to the modern synthesis theory; a comprehensive theory of evolution that integrated ideas from many fields.
How are substrates like keys and enzymes like locks?
Enzymes have an active site that is specific for a substrate - therefore enzymes only work when the right substrate is present. The surfaces of the enzyme and the substrate fit together - like a lock and key - allowing the enzyme to fulfil its function. The theory of "induced fit" is more widely accepted - it is similar, but the enzyme shape changes to accommodate the substrate.
