Answer:
Bioenergetics is the part of biochemistry concerned with the energy involved in making and breaking of chemical bonds in the molecules found in biological organisms. It can also be defined as the study of energy relationships and energy transformations and transductions in living organisms.
Answer:
analogous trait
Explanation:
Analogous traits or structures are the ones that develop as a result of convergent evolution between the distantly related species. The members of these species develop the same features to become adapted to similar environmental conditions. These analogous traits are not present in their ancestors. For example, bats and insects have wings to assist them in flying. However, the wings in bats and insects have a different basic structure.
Answer;
Simple diffusion does not require energy.
Explanation;
Passive transport is a type of transport that does not require energy since it lets diffusion move molecules only down their concentration gradient.
Simple diffusion, osmosis, and facilitated diffusion are examples of passive transport.
Answer:
This question lacks options, the options are:
A. ATP synthesis
B. Oxidation of water
C. Carbon fixation
D. Electron transport
The answer is C. carbon fixation
Explanation:
Photosynthesis, which is the process whereby green plants synthesize their food (sugar) in the presence of sunlight, occurs in two major stages namely: light dependent reaction and light independent reaction. As their name implies, the former must occur in the presence of light while the latter need not occur in the presence of light.
The light dependent reaction, which occurs in the thylakoid membrane of the chloroplast, involves the synthesis of ATP and NADPH molecules needed for sugar production in the light independent stage. Generally, light photon strikes a pigment called CHLOROPHYLL making it excited to split water molecule (photolysis). The protons (H+) and electrons produced are used to synthesize ATP and NADPH respectively. Hence, the following processes occurs in the light dependent stage: ATP synthesis, Oxidation of water, Electron transport etc.
Note that, CARBON FIXATION takes place in the second stage, which is the light independent stage.
Answer:
23 chromosomes
Explanation:
Human sex cell (either male or female sex cell) is haploid and consists of half of the total number of chromosomes within a cell.
So if there are 46 chromosomes in a cell, a human egg will have exactly half of it i.e 23 chromosomes.
During mating, 23 chromosomes are donated by both father and mother to their offspring (diploid zygote) to constitute 46 chromosomes set.
