Answer:
Pulse chase experiment was performed to find the secretory pathway of proteins inside the cell. The protein sorting and pathway of protein can easily be studied by the pulse chase experiment.
The molecule is labelled with radioactive component and its pathway is observed during the pulse chase experiment. The molecule reside 5 minutes in rough ER. After this 40 minutes in glogi apparatus. From the golgi apparatus the molecules moves towards the endosomes and resides for 70 minutes. The molecules then transferred to lysosomes in 140 minutes. This chasing explains the pathway of the molecule.
The pathway can be drawn is ER→golgi→endosome→lysosome.
The changes in foot structure in a bird population over. Evolution leads to less complex organisms. And also the lock-and-key model.
A physical environment with different species that interact with one another and with non-living thing is called an ecosystem
Answer:
The correct answer would be mitosis or M phase.
Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.
It is primarily divided into four stages:
- Prophase
- Metaphase
- Anaphase
- Telophase.
It results in the equal distribution of chromosomes into two daughter cells.
It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.
Answer:
There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding
Explanation:
An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.
Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding.
